Checklist 5: Actions for load-source disk unit failure

The checklist shows the sequence of steps to use to recover after a failure on a load-source disk unit with complete data loss. A user auxiliary storage pool was configured, and the basic user ASP overflowed.

The checklist is used for the following problem situation -

Failed unit: Load source unit
Data loss: All
User ASP is configured: Yes
Basic user ASP overflowed: Yes

Attention: When you replace a disk unit in your system auxiliary storage pool (ASP), the system loses addressability to the objects in your basic user ASPs. Recovering object ownership for objects other than document library objects (DLOs) requires manually assigning ownership for every object in every basic user ASP. You might want to treat this situation as a total recovery and restore all your information from your save media if the following conditions are true:

You have many objects in your user ASPs
You thoroughly backed up your system

Run the steps that are described in Checklist 20: Recovering your entire system after a complete system loss to recover your system.

Table 1. Recovering from a disk failure–Checklist 5
Task	What to do	Where to read more about it
Actions run by the service representative
___ Task 1	Attach the new disk unit.
___ Task 2	Prepare to load the Licensed Internal Code by using the most recent Save System (SAVSYS) media.	Preparing for loading the Licensed Internal Code.
___ Task 3	Install the Licensed Internal Code by selecting option 3 (Install Licensed Internal Code and Recover Configuration).	Loading the Licensed Internal Code.
___ Task 4	Recover the disk configuration (assignment of disk to ASPs and protection).	Recovering your disk configuration.
Actions run by the user
___ Task 5	If you are using an encrypting tape drive, verify that the Encryption Key Manager (EKM) is running and connected to the tape library before you begin the recovery operation. The EKM contains the encryption keys that are needed for the recovery operation. Skip this step if you are not using an encrypting tape drive.	rzarmencryptrecovertape.htm
___ Task 6	Restore the operating system, beginning with Task 1: Starting to restore the operating system. You are running a complete restore operation.	Restoring the operating system, task 1 through task 6.
___ Task 7	If you are restoring from an encrypted backup, the save/restore master key on the target system must match the save/restore key on the source system. If the save/restore master key does not match, set the target system's save/restore master key to recover all the master keys.	Recovering from an encrypted backup using software encryption and Loading and setting save/restore master key in the Cryptography IBM i documentation topic.
___ Task 8	If you restored the operating system from distribution media, some system information might be reset to default values, such as access path recovery times and the system reply list. Verify these values and correct them if necessary.	Recovering system information.
___ Task 9	If necessary, change the QALWOBJRST system value. Write the old value here: ___________	Controlling restoration of security-sensitive objects.
___ Task 10	If necessary, change the QVFYOBJRST system value. Write the old value here: ___________	Controlling restoration of security-sensitive objects.
___ Task 11	If necessary, change the system value that controls whether the job log wraps when it is full. Use the Work with System Values command: WRKSYSVAL QJOBMSGQFL. Write down the current value here: ___________. Then change the value to *PRTWRAP.	The System values topic in the IBM i documentation.
___ Task 12	After the system values are changed, sign off by using the command SIGNOFF *LIST. Then, using a newly created password, sign back on as QSECOFR for the new values to take effect.	Describing the contents of your user auxiliary storage pools.
___ Task 13	Describe or diagram, as much as possible, the contents of your user ASPs before the failure.	Describing the contents of your user auxiliary storage pools.
___ Task 14	Recover user profiles, configuration, libraries in the system ASP, and the contents of the user ASPs that were not in overflowed status. If you choose not to restore all of your libraries now, verify that you restore the QGPL and QUSRSYS libraries along with the libraries that you are restoring.	Recovering a basic user auxiliary storage pool (ASP) after recovering the system ASP, task 1 through task 11.
___ Task 15	Recover the objects in the user ASPs that were overflowed.	Recovering a damaged basic auxiliary storage pool, task 1 through task 9.
___ Task 16	Restore document library objects to the system ASP and to any overflowed user ASPs with DLOs.	Restoring documents and folders.
___ Task 17	Restore your last complete save of directories.¹	Restoring objects in directories.
___ Task 18	If you have user-defined file systems (UDFSs) in user ASPs that do not restore correctly, you might need to run other recovery steps.	Task 7: Restoring user-defined file systems to the user auxiliary storage pool.
___ Task 19	Restore changed objects and apply journaled changes.	Restoring changed objects and apply journaled changes.
___ Task 20	Update program temporary fix (PTF) information for all PTF save files in the QGPL library by typing: UPDPTFINF.	Restoring changed objects and apply journaled changes.
___ Task 21	If the Save System Information (SAVSYSINF) command was used, then run the Restore System Information (RSTSYSINF) command. The Restore System Information (RSTSYSINF) command restores a subset of the system data and objects that are saved by using the Save System Information (SAVSYSINF) command.	Restoring system information.
___ Task 22	Restore authority. Type - `RSTAUT`	Restoring object authorities.
___ Task 23	Reapply any PTFs that were applied since your last SAVSYS operation.	Restoring program temporary fixes (PTFs).
___ Task 24	If necessary, use the WRKSYSVAL command to change the QALWOBJRST system value back to its original value.	Controlling restoration of security-sensitive objects.
___ Task 25	If necessary, use the WRKSYSVAL command to change the QVFYOBJRST system value back to its original value.	Controlling restoration of security-sensitive objects.
___ Task 26	If necessary, change the QJOBMSGQFL system value back to its original value by using the WRKSYSVAL command.	System values.
___ Task 27	Run one of the following commands - `SIGNOFF LIST` `DSPJOBLOG *PRINT` Check the job log to verify that all objects were restored. The job log contains information about the restore operation. To verify that all objects were restored, spool the job log for printing along with the job's remaining spooled output, if any. Message CPC3703 is sent to the job log for each library that was successfully restored. Message CPF3773 is sent to indicate how many objects were restored. Objects are not restored for various reasons. Check for any error messages, correct the errors, and then restore those objects from the media.
___ Task 28	Do a normal initial program load (IPL) now.	Performing a normal initial program load.
___ Task 29	If IBM Content Manager OnDemand for i is installed, complete journaling for Content Manager OnDemand by typing the following commands - `CALL QRDARS/QRLCSTRJ PARM('RLC') CALL QRDARS/QRLCSTRJ PARM('RLR')`
___ Task 30	If you have the Cryptographic Device Manager licensed program, 5733-CY2 or 5733-CY3, installed, run this command: `CALL QCCADEV/QCCAELOAD`
___ Task 31	Review job logs or output from your restore operations to verify that all objects were restored successfully.	Verifying whether objects are restored successfully.
