PATCH OVERVIEW
Name:NB_PDE_6.6.1.2
Date:February 25,2011
This Hotfixprovides features andfixes tothe Symantec NetBackupPureDisk6.6.1
software.
PREREQUISITES
This Hotfix can be installed on PureDisk 6.6.1 or PureDisk 6.6.1.1 software.
For detailed information about the PureDisk 6.6.1.2 Hotfix,refer to the the
following site:
http://www.symantec.com/business/support/index?page=content&id=TECH153564
Note:PureDisk automatically creates upgrade jobs for the agent software on
backup and restore clients.The upgrade does not create agent upgrade jobs for
PDDO (deduplication) agents on NetBackup media server clients.To upgrade
mediaserver clients,followtheprocedureUPGRADINGDEDUPLICATIONAGENTS
ONMEDIA SERVER CLIENTS in this document.
ENHANCEMENTS
The following list of enhancements provides an overviewof the improvements
that are included in this release of PureDisk.See the PRODUCT FIXES section of
this README file for specific details about these enhancements.
■ Performance improvements
■ Replication
WithPDDOenabled,replicationperformance is significantlyimprovedfor
optimized duplication fromNetBackup to PureDisk servers.This
enhancement removedoverheadfromthe PureDiskstorage pool authority
(SPA).
■ Concurrent backup and data removal
With PureDisk 6.6.1.2,you can run backup jobs and data removal jobs at
the same time.With past releases,data removal jobs could not run
concurrently with backup jobs.In some environments data removal jobs
did not run because backup jobs ran 24 hours per day.
■ Rollup of existing EEBs
PureDisk 6.6.1.2 includes all engineering binaries that have been created for
PureDisk 6.6.0.3 and PureDisk 6.6.1.
■ Vulnerabilities resolved
PureDisk 6.6.1.2 resolves a number of identified vulnerabilities.See the
VULNERABILITIES - RESOLVEDsection of this README file for specific
details.

PRODUCT FIXES
This release contains the following product fixes:
■ Etrack 2084551:PDDOoptimized duplication forces unnecessary PDVFS
directory cache loads resulting in degraded performance
After the initial setup of the environment,some customers reported slow
replications when using storage lifecycle policies (SLPs).SLP polices were
beingusedfor the replicationof the data betweenPureDisknodes.The PDVFS
directory cache was being reloaded many times in an optimized duplication
replication.Tofixthis issue,analternate approachwas implementedtoquery
the metabase directly and bypass the directory cache load.
■ Etrack 2162355:PDDOgenerates a large number of temporary files in/tmp
or/var/tmp
When PDDOis configured for a particular storage pool,but that storage pool
is not available due to error conditions (or it is turned off),a PureDisk register
attempt is performed.However,it is not cleaning up the files correctly after
it completes.In PureDisk 6.6.1.2,this error handling uses different logic that
resolves this issue.
■ Etrack 2143000 and Etrack 2161043:PureDisk 6.6.1 and PureDisk 6.6.0.3 are
not backwards compatible because of missing getNBUPrimaryDSIDlogic on
target SPA
PureDiskreleases 6.6.0.3and6.6.1were not backward-compatible insituations
where optimized duplication was used with a PureDisk 6.6.0.3 source storage
pool and a PureDisk 6.6.1 target storage pool.With the fix,PureDisk 6.6.0.3
can performoptimized duplication to PureDisk 6.6.1.2.
■ Etrack 2103458:PDDOconfigurable Web service call retries
The followingWebservice call parameters are nowconfigurable inthe pd.conf
file.
■ The WS_TIMEOUT parameter allows you to increase or decrease the timeout
valuefor Webservicecalls madefromNetBackupmediaservers toPureDisk
storage units.The default value for this parameter is 120 (seconds).
■ TheWS_RETRYCOUNTparameter allows youtoconfiguretheamount of retries
that will be attemptedincase the Webservice fails or times out.The default
value for this parameter is 3 (retries).
■ Etrack 2125623:PDDOreplication sets encryption by default
Optimized duplicationencryptionis enabled by default inPDDO,but pd.conf
states it is disabled by default with OPTDUP_ENCRYPTION.To resolve this issue,
the parameter OPTDUP_ENCRYPTION is set nowto off in pd.conf.
5Symantec NetBackup PureDisk Release 6.6.1.2 Readme
PRODUCT FIXES
■ Etrack 2141136:Enable backup policy compression by default
When creating a newPureDisk backup policy,compression is nowenabled by
default.This change applies to all backup policy types.Policies created with
earlier releases are not changed.Policies created with PureDisk 6.6.1.2 and
later releases nowenable compression by default.
■ Etrack 2163363:NetBackup optimized duplication job is failing with error
no-50 {Client Process Aborted}
Resolves an issue when a PDDOreplication job successfully finished very
quickly after being created,but NetBackup did not validate the job with a
proper job exit code.
■ Etrack 2093695:Jobs hang if the import PO-List process on the metabase
engine and data mining attempted to access the same data selection at the
same time
Fixes a problemfound when a PureDisk environment locked up and jobs were
not progressing.Symantec traced the problemto a data mining process that
attempted to access a data selection at the same time it accessed an import
process.The processes stopped and did not progress until one or the other
was stopped.As a result,all backup jobs eventually locked up as the number
of hung import processes reached the concurrency limit.
■ Etrack 2101259 and 2101261:Rerouting failure -"Could not process tlog
entries:invalid argument"
Fixes aproblemthat occurredwhenreroutingfailedinenvironments withtwo
or more content routers that tried to add one or more content routers.
■ Etrack2111731:Move'ChangeIPTables'fromcronto/etc/init.d/pdiptables
Moves'ChangeIPTables'fromcron to/etc/init.d/pdiptables.
ChangeIPTablesnolonger runs everyfiveminutes fromcron;ChangeIPTables
runs onlywhen"pdiptables change"is run.The"pdiptables start"process
loads the firewall rules.The"pdiptables stop"process removes the firewall
rules.
■ Etrack 2116235:Call to pdengine (PHP) in GetFilesAction.php picks up
configuration fromsystemif another version of PHP is installed and restore
fails
Fixes a restore problemon Windows clients that also hosted PHP.When
Windows clients had PHP installed,backups completed successfully,but
restores failed with the following PHP errors:

Fixes the PureDisk 6.6 administrative Web UI logon page so that it accepts
passwords that containthedollar sign($) character for external LDAPaccounts
residing in Active Directory domains.
■ Etrack 2160714:Add configuration file options for non-fatal exports
An option to enable or disable non-fatal exports was added to the agent.conf
file that will allowexport jobs to continue if non-fatal errors occur.The
parameter nonfatalexporthas a default value of 0.This value means that the
export stops only if a fatal error occurs.
■ Etrack 2166739:Backups are failing with"Error:22:SortPOListFile:source

■ Etrack 2141137:Enable MBGC extensive cleanup by default
With PureDisk 6.6.1.2,metabase garbage collection extensive cleanup is by
default enabled to accommodate an ever-growing metabase engine database.
■ Etrack 2150461:PureDisk 6.6.1 install/upgrade wizard screen includes two
extraneous options
The PureDisk6.6.1installationandupgrade screenprovides five boot options.
The boot screenprovides these options at everyboot,not onlyduringthe 6.6.1
upgradeprocess.Theappearanceandwordingof theseoptions confusedsome
users.To resolve the confusion,two options were removed fromthe screen,
and the text of the options was altered to clarify the options.With PureDisk
6.6.1.2,the following boot options appear on the installation and upgrade
screen:
■ PDLinux 6.6.1 (default)
Use the SMP kernel (for multiple CPUs) to boot the machine.
■ Failsafe -- PDLinux 6.6.1
Use SMP kernel's safe mode to boot the machine.This option is similar to
Windows'safe mode.
■ Floppy
Use a floppy disk to boot the machine.
■ Etrack 2169703:Container lost by running dcscan
Fixes aproblemwhere,insome cases,adatacontainer canbe lost if the support
tool dcscan is used while compaction is running.
■ Etrack 2181557:Unable to delete PureDisk client agents -"Failed LDAPdelete
of user"
This error occurredwhenattemptingtodelete anyPureDiskclient agent using
the PureDisk 6.5.1.2 user interface.This issue is resolved in PureDisk 6.6.1.2.
■ Etrack 2185567:DerefCR.php fails to finish and causes a storage leak
While executing a data removal policy,the DerefCR.php function is called
when some invalid fingerprints are found.In this case,PureDisk generates
the message “Fatal error,undefined function tempname” and exits.Though
the operation is not be executed in the content router,the path objects (POs)
were being updated as"dereferenced"in the metabase.This caused a storage
leak.With PureDisk 6.6.1.2,this problemhas been fixed.
■ Etrack 2196263:Lowdeduplication rates on PDDObackups after upgrading
from6.5.1.2 to 6.6.1
After upgrading to 6.6.1 from6.5.1.2,some systems experienced lower
deduplicationrates (around25-30%) withPDDObackups.Subsequent backups
also showthis lower deduplication rate as well.With PureDisk 6.6.1.2,this
problemhas been fixed through a number of code enhancements.

PRODUCT FIXES
■ Etrack 2193759:Rerouting failed with assertion error
Resolves a problemon systems with multiple content router nodes and a
PDDO-enabled environment where rerouting processes failed on the nodes
due to an assertion error.
■ Etrack 2050594:PDServer agent segmentation fault on MBE node of primary
PDDOSPA
Corrects a problemthat results in a server agent crash.The server agent
crashed when the following series of events occurred:
1 - The agent issued a'syncState'call to the workflowengine.
2 - A process was running on agent side.
3 - The process was not marked as running in workflowengine cache.

■ Etrack 1966553 &Etrack 1977075:Replication jobs that wait for import
replication data selection step to complete cause performance issues
■ Increases thepo_count_thresholdparameter andthepo_size_threshold
parameter.This improvement decreased the number of remote metabase
import jobs that resided on the destination storage pool.As a result,
replication jobs launch only one import replication job on remote agents
and complete faster with less load on the storage pool.For
po_count_threshold,the default value is 200000.For po_size_threshold,
the default value is 200000000000 (200 GB).To access the Server Agent
configuration file fields,click as follows in the administrative Web UI and
then click the configuration value you want to change:

Also with this fix,20 PDDOreplication jobs can run simultaneously.
■ Etrack2084537:PDDOreplicationgets queuedupbecauseof longimport times

PureDisk 6.6.1.2 uses a metabase web service to import image POs in remote
replicatedPDDOdata selections.Previous releases usedmetabase import jobs.
Import replicationdata selectionjobs are no longer createdonthe destination
storage pool when PDDOreplication is initiated fromthe NetBackup PDDO
plug-in.
■ Etrack 2069901:Create_dslastpddo rewrite dslast_pddo views as well as data

PRODUCT FIXES
Thetransferratefor somereplicationjobdetailsreportsmight be inconsistent
with expectations because the short duration of a backup could cause a spike
in the data transfer rate before the throughput is stabilized.With PureDisk
6.6.1.2,the actual data transfer rate has been added to the job details to help
account for suchreportinginconsistencies.The followingis anexample of the
line added to the log:
[stream0]..Info:Network transfer rate:3.20 MB/sec
■ Etrack 2186502:Restore bandwidth not being throttled
Adds a newparameter to the restore wizard:Maximumallowed bandwidth
(KB/s) This value is set per stream,and it appears in the restore job log as
follows:
"*** Bandwidth limit set to XX KB/s via policy"
KNOWN ISSUES
The following are the known issues associated with this patch:
■ Etrack 2294093:Rollback UI hangs while rolling back fromPureDisk 6.6.1.2
to PureDisk 6.6.1
When rolling back a PureDisk version fromrelease 6.6.1.2 to release 6.6.1
using the storage pool configuration wizard (also known as the installer UI),
the UI hangs after approximately83%of the operationcompletes eventhough
the rollbackoperationactuallycompletes successfully.The followingrollback
progress messages appear before the UI hangs:
+ Stopping services on all nodes
+ Validating restore conditions
+ Restoring checkpoints
+ Restoring/opt on all nodes
Workaround:If the installer UI hangs for several minutes and the rollback
progress is 83%or more complete,close the installer UI because patch has
beenrolledbackat this point.Make sure that the UI hangs for several minutes
before you close the windowto allowany background operations to complete.
■ Etrack 2194531:Unable to upload large patch tar file (more than 250M) to
server by using the storage pool configuration wizard
When the size of the patch tar file is greater than 250M,the storage pool
configuration wizard user interface (UI) is not able to upload the file to the
storage pool authority (SPA) node for installation purposes.
Symantec NetBackup PureDisk Release 6.6.1.2 Readme
KNOWN ISSUES
12
Workaround:Symantec provides a script to allowa large file to be uploaded
for installation.To run this script and install the PureDisk 6.6.1.2 tar patch
using the storage pool configuration wizard (also known as the installer UI),
performthe procedure"Applying preinstallation updates to the storage pool
configuration wizard"in the PREINSTALLATIONSTEPS section of this
README file.
■ Etrack 2220813:Statistics tab of PDDOjob details is blank onPureDisk 6.6.1.2
SPA
The Statistics tab of the Job Details windowdoes not contain data for PDDO
jobs that run on a PureDisk 6.6.1.2 storage pool authority (SPA).
Workaround:Complete the following steps to allowviewing of data in the
Statistics tab:
■ Stop the PureDisk administrative Web UI:
/etc/init.d/puredisk stop pdgui
■ Run the following command to delete the
/opt/pdgui/tomcat/webapps/PureDisk folder:
/bin/rm -fr/opt/pdgui/tomcat/webapps/PureDisk
■ Start the PureDisk administrative Web UI:
/etc/init.d/puredisk start pdgui
■ Etrack 2221889:Percentage of deduplication is not shown properly for a
PureDisk6.6.1.2storage pool authority(SPA) if the plug-inis at PureDisk6.6.1
level
If you upgrade the storage pool authority (SPA) to PureDisk 6.6.1.2 and then
leave the deduplication agent at an earlier software release,deduplication
rates are not displayed correctly in the PureDisk administrative Web UI.This
issue is applicable only if the deduplication agent runs on a NetBackup 6.5.x
media server.
Workaround:Upgrade the deduplication agent to the latest release,PureDisk
6.6.1.2.See"UPGRADINGDEDUPLICATIONAGENTS ONMEDIA SERVER
CLIENTS"in this README file for instructions.
■ Etrack 2225843:PDDOconfiguration and PDDObackups still succeed when
PDis in checkpoint mode
PureDisk 6.6.1.2 does not suppress PDDOoperations in checkpoint mode.
Checkpoint mode is the state that a storage pool is in if you installed a patch,
createdacheckpoint,but didnot commit the patch.Typically,PureDiskshould
prevent PDDOoperations fromoccurringwhile astorage pool is incheckpoint
mode.For more information about checkpoint mode,see the Symantec
NetBackup PureDisk Administrator's Guide,Release 6.6.1.
13Symantec NetBackup PureDisk Release 6.6.1.2 Readme
KNOWN ISSUES
Workaround:If you roll back PureDisk 6.6.1.2,all changes and all backups
written to the storage pool while in checkpoint mode are lost.Symantec
strongly recommends that you do not performany production backups while
the storage pool is in checkpoint mode.When in checkpoint mode,Symantec
recommends that you restrict backup activity to only test backups and that
younotify appropriate NetBackupadministrators inyour organizationof this
situation.This recommendationapplies toall storagepools,bothPDDOstorage
pools and remote office storage pools.Performthe procedure"Applying
preinstallation updates to the storage pool configuration wizard"in the
PREINSTALLATIONSTEPSsectionof this READMEfile so that messages that
can caution you about using the checkpoint mode properly can be displayed.

INSTALLATION INSTRUCTIONS
This section describes howto install the software.
Installing the patch
1 Logintothe PureDiskadministrative WebUI andmake sure that noPureDisk
jobs are currently running or are scheduled to be run.
■ Select"Monitor >Jobs".
■ In the right pane,select the jobs you want to terminate.
■ Select"Stopjobgracefully"or"Stopjobimmediately".
You might lose data if you select"Stopjobimmediately".
■ Confirmthe termination in the pop-up windowthat appears.
Refer to the topic"Terminating a job that is running"inthe PureDiskBackup
Operator Guide,Release 6.6.1,or in the online Help for more information
about stopping PureDisk jobs.
2 (Conditional) If you have/Storage partitions that are mounted on an NFS
share,add an entry for each partition to the/etc/fstab file.
Note:NFS is supported in a PureDisk environment only with specific
limitations and requirements.See the topic"Limitations for PureDisk 6.6
with NFS"in the PureDisk Getting Started Guide,Release 6.6.1,or contact
technical support for more information about NFS support in PureDisk.
3 Log out fromthe PureDisk administrative Web UI.

4 (Conditional) Freeze the PureDisk service groups for the clustered PureDisk
server.
Performthis step if the storage pool is installed with Veritas Cluster Server
(VCS) software.
For each active node,you have groups such as pd_group1,pd_group2,and
so on.Log onto the Storage Pool Authority (SPA) node and runthe following
command for each of these groups:
/opt/VRTS/bin/hagrp -freeze pd_group1
Where pd_group1 indicates the group you are freezing.
For information about howto freeze and unfreeze clustered storage pools,
see the Symantec NetBackup PureDisk Storage Pool Installation Guide.
5 Type the following command to unpack the Hotfix software:
tar -C/-xf/root/NB_PDE_6.6.1.2_NNNNNN.tar./opt
6 Type the following command to run and install the Hotfix:
/opt/pdinstall/apply-NB_PDE_6.6.1.2.sh
If the topology.ini file is encrypted,the software prompts you for the
password to decrypt this file.
The Hotfix automatically pushes the software to all nodes inthe storage pool
and to all clients.
Note:The Veritas Cluster Server (VCS) software might detect some faults
during the upgrade process.If any upgrade actions generate a VCS fault,use
the Cluster Manager Java Console to clear the fault and probe that resource
group before you unfreeze the cluster.
At the end of a successful installation,the software prompts you to encrypt
the topology.ini file.
When the upgrade script completes successfully,the script also unfreezes
the PureDisk service groups for the clustered PureDisk server.
7 (Conditional) Again,freeze the PureDisk service groups for the clustered
PureDisk server.
See Step 4 for instructions about freezing PureDisk service groups.
