Frequently Asked Questions - IBM i Agent

Can I stop automatic delivery of updates from the access node to my IBM i Agent client?

Yes. You can block updates delivery to an IBM i Agent client by configuring the blockUpdate additional setting on the access node. By default, updates are pushed automatically during the next communication session between the access node and the IBM i Agent client.

  • To the client, add the additional setting as shown in the following table.

    For instructions on how to add additional settings from the CommCell Console, see Add or Modify an Additional Setting.

Can I back up IBM i Agent security information and system configuration data?

Yes. When you run a backup of the default subclient or custom subclient with predefined backup item Security Objects and Configuration Objects are selected. You can see the IBM i File System security information and system configuration data in the Browse and Restore window with the following node names:

  • <System Security>

  • <System Configuration>

<System Security>

The System Security folder will show a list of user profiles along with a specific file - *ALL - Security Attributes.

You can restore a single or multiple user profiles.

You can restore all of the security attributes (user profiles and authorization lists) by selecting the file - *ALL - Security Attributes.

When you restore a <System Security> folder, all of the security information will be restored.

The Restore Authority (RSTAUT) command automatically runs at the end of the restore job when user profiles are restored.

Using the save file generated by the <System Security> objects restore job, you can restore all the user profiles, authorization lists and authority holders from the command line :

From a valid IBM console, type the following command:

CVLIB/CVRSTSECD SAVF(CVLIBOBJ/ALLUSRPRF) SAVFDEL(*YES) SBSSTART(*YES) SECDTA(*USRPRF)

where CVLIBOBJ/ALLUSRPRF is the save file name generated by the <System Security> objects restore job on the IBM i Agent client.

You can use any of the following values for the SECDTA parameter:

  • *USRPRF: Restores the user profiles and their private authorities.

  • *PVTAUT: Restores the private authorities for the specified user profiles, and the auxiliary storage pools. The Restore Authority (RSTAUT) command uses this information to restore the authorities to the referenced objects.

  • *PWDGRP: Restores the specified user profiles, their private authorities, and their passwords and group linkages.

    This command performs the following tasks:

  • Sends an inquiry message to QSYSOPR message queue to acknowledge the restore process. Once the message is acknowledged, IBM i system will go to restricted state.

  • Save file CVLIBOBJ/ALLUSRPRF will be deleted unless the parameter SAVFDEL is set to *NO.

  • Subsystems automatically start after the restore process based on the start-up program mentioned in the IBM i system value QSTRUPPGM unless the parameter SBSSTART is set to *NO.

  • The RSTAUT command automatically runs at the end of restore job.

<System Configuration>

The System Configuration folder will show a list of configuration objects along with a specific file - *ALL - Configuration.

You can restore a single or multiple configuration objects.

You can restore all of the configuration objects by selecting the file - *ALL - Configuration.

The Restore Configuration (RSTCFG) command is used with options OBJ(*ALL) OBJTYPE(*ALL) SRM(*NONE), where

  • OBJ = objects

  • OBJTYPE = object types

  • SRM = system resource management objects

    When you do a full system restore (/) or select the <System Configuration> folder to restore, all of the configuration objects will be restored.

Why did an object I deleted still show up in the browse operation after an incremental backup job?

If you delete an object and run an incremental backup job, and if no other object is selected for the actual backup job, the deleted object will not be immediately processed. The deleted object is processed the next time you run a backup job and there are objects to back up.

How do I run the Commvault services on a different subsystem?

You can specify the subsystem when you install the IBM i Agent. The default subsystem is QSERVER.

  • To change the subsystem that the Commvault jobs run, type the following on the command line

    CVLIB/CVCHGJOBA SBSD(Subsystem_Library/Subsystem_Description) JOBQ(Job_Queue_Library/Job_Queue)

Example of how to make Commvault jobs run on the QCTL subsystem with the default jobq

FAQ - Can the Commvault Software Protect DB2 files on IBM i?

The Commvault software backs up the physical files (PF) and logical files (LF). If the DB2 files for a single application are distributed in multiple libraries, use the SYNCLIB option on the Save While Active tab of the Subclient Properties dialog box.

When the logical files and physical files are in different libraries, you must restore the physical files before you restore the logical files, or use the DFRID advance restore option. For more information, see Performing an IBM i Agent Restore to a New Library, Directory or Folder.

How can I perform an incremental backup after a full backup has run on a flash-copied machine?

This procedure describes how to perform incremental backups on a flash-copied IBM i client.

Note

Only support or administrative personnel should perform this procedure.

Step 1: Synchronize Commvault Job Results Directory

  1. Copy the Commvault job results directory from the flash-copied IBM i client back to the primary (source) IBM i client from which the data was originally created using FlashCopy.

  2. Ensure this synchronization is completed after all backups for the day and before initiating the next FlashCopy operation.

Step 2: Configure Incremental Backup to Use Object Changed Time as Reference

  1. On the original IBM i client machine, set the nUseMaxFileCTimeAsRefTime software parameter. This ensures that objects changed on the IBM i client after the FlashCopy operation and before the Commvault full backup starts are included in the subsequent incremental and differential backups.
Procedure to Set the Software Parameter

  1. On the IBM i File System Agent host, open the 5250 terminal and run the command:

    COMMVAULT CONFIG

  2. On the initial screen, select the IDA option (2) to set the properties.

  3. Set the nUseMaxFileCTimeAsRefTime parameter to 1.

  4. Type q to return to the previous menu, and then exit the program.

How frequently should a full backup be run for IBM i subclients?

For IBM i subclients, it is recommended to perform weekly full backups, or at a minimum, one full backup every 10 days. This practice helps minimize the need to retrieve data from multiple backup jobs within a backup cycle when restoring a library or object.

Do I need to configure anything on the IBM i client after upgrading the client operating system?

If the Commvault services are configured to run in any of the IBM shipped subsystems before the operating system upgrade, the subsystem descriptions might change to shipped values and the Commvault configuration associated with the subsystem description might be lost or corrupted. In such cases, Commvault services might fail to start on the IBM i client.

To fix the configuration associated with the subsystem where the Commvault jobs run, run the following command on the command line:

 
CVLIB/CVCHGJOBA SBSD(subsystem_library/subsystem_description) JOBQ(job_queue_library/job_queue)

For example, if the services fail to start after upgrading the operating system, to set the subsystem configuration components with the default subsystem QSERVER, run the following command:

SBSD(QSYS/QSERVER) JOBQ(QSYS/QPWFSERVER)

How can I back up and restore the objects that contain a "/" in the object name?

To back up objects that contain a forward slash ("/") in the name, use optimized scan. To restore such objects, restore the entire library, and select the Unconditional Overwrite option if the destination library contains an object with the same name.

How can I restore all user data from one IBM i client to another IBM i client that has the operating system installed?

To restore user data in an IBM recommended sequence, use the Full Data Recovery option at the backup set level. For more information, see Performing an IBM i Agent Full Data Restore Operation.

Why do the sizes of libraries or objects appear larger when browsing the content of an optimized scan backup?

Optimized Scan does not collect statistics on individual objects within libraries. It uses the size reported by the save command/API. Therefore, a content browse might display a different library size than the actual size on the IBM i client machine.
