Checklist 13: Actions for a failure in a basic auxiliary storage pool disk unit

This checklist shows the sequence of steps you should use to recover after basic auxiliary storage pool (ASP) has overflowed and all data has been lost.

This checklist should be used for the following problem situation:

Failed unit:: Basic ASP in overflow status
Data loss:: All

Before you begin your recovery, make a copy of this checklist. Fill in the appropriate areas as you and the service representative perform the recovery steps. This checklist provides an important record of your recovery actions. It can help you to diagnose any problems that occur after the recovery. It might also be useful in evaluating your backup strategy.

Most steps in the checklist include references to other topics in this document. Refer to these tasks if you need more information about how to perform a particular step. You might not need to perform some steps, such as restoring changed objects, if they do not apply in your situation.

Table 1. Recovery checklist for disk failure–Checklist 13
Task	What to do	Where to read more about it
Actions to be performed by the service representative
___ Task 1	Physically remove the failed disk unit from the system.
___ Task 2	Delete the data in the ASP that contains the failed unit.
___ Task 3	Install the replacement disk unit.
___ Task 4	Configure the replacement disk unit by selecting the Replace configured unit function on the Work with Disk Units display.
Actions to be performed by the user
___ Task 5	You must perform an initial program load (IPL) at this time. Follow the procedure for starting the system after it ends abnormally.	Starting the system after it ends abnormally.
___ Task 6	Reclaim storage.	Reclaim Storage (RCLSTG) command.
___ Task 7	Delete the overflowed objects.	Deleting overflowed objects during recovery.
___ Task 8	If necessary, change the QALWOBJRST system value. Write the old value here: ___________	Controlling restoration of security-sensitive objects.
___ Task 9	If necessary, change the QVFYOBJRST system value. Write the old value here: ___________	Controlling restoration of security-sensitive objects.
___ Task 10	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 11	After changing the system values, 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.
___ Task 12	Recover the objects in the basic ASP.	Recovering a damaged basic auxiliary storage pool, task 1 through task 9.
___ Task 13	If you have user-defined file systems (UDFSs) in user ASPs that do not restore correctly, you might need to perform additional recovery steps.	Task 7: Restoring user-defined file systems to the user auxiliary storage pool.
___ Task 14	Restore changed objects to the basic ASP. Apply journaled changes to objects in the basic ASP.	Restoring changed objects and apply journaled changes, task 1 through task 7.
___ Task 15	Restore authority. Type: `RSTAUT`	Restoring object authorities.
___ Task 16	If necessary, change the QALWOBJRST system value.	Controlling restoration of security-sensitive objects.
___ Task 17	If necessary, change the QVFYOBJRST system value.	Controlling restoration of security-sensitive objects.
___ Task 18	If necessary, change the QJOBMSGQFL system value back to its original value by using the WRKSYSVAL command.	System values.
___ Task 19	Perform either a: `SIGNOFF LIST` or a `DSPJOBLOG *PRINT` Check the job log to ensure 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 tell you 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 20	You must perform a normal IPL at this time.	Performing a normal initial program load.
___ Task 21	Review job logs or output from your restore operations to ensure that all objects were restored successfully.	Verifying whether objects are restored successfully.
