5.6 Checking Volumes

If necessary, use the VOLUTIL utility to add system volumes, that is, the system domain (MPEXL_SYSTEM_VOLUME_SET) disk drives (except LDEV1). For more information on VOLUTIL commands, refer to the Volume Management Reference Manual.

To check volumes:

From the console, log on with the following conditions (if you are not already logged on).
:HELLO MANAGER.SYS,INSTALL;HIPRI :SPOOLER LP;START :STREAMS streams_device
A common streams_device value is 10. An LP device must be configured in SYSGEN. Already spooled and streamed messages might display.

Enter a DSTAT ALL command to verify a status of member for the disk drives.

:DSTAT ALL

Sample output:

LDEV-TYPESTATUSVOLUME (VOLUME SET - GEN)
--------- -------------- 
-----------------------------
1- 022040MASTERMEMBER1(MPEXL_SYSTEM_VOLUME_SET-0)
2- 
022040LONERMEMBER2(MPEXL_SYSTEM_VOLUME_SET-0)

All system volumes showing a status of LONER must be added using the VOLUTIL utility. Add system volumes using SCRATCHVOL and NEWVOL commands. For example:

:VOLUTIL
volutil: SCRATCHVOL 2
Verify: Scratch 
volume on LDEV 2 [Y/N]? Y
volutil: NEWVOL MPEXL_SYSTEM_VOLUME_SET:MEMBER2 
2 100 100
Initialize VOLUME mpexl_system_volume_set:MEMBER2 
on LDEV 2 with PERMANENT SPACE = 100% and TRANSIENT SPACE = 100%? 
Y
volutil: EXIT

Check all volumes to confirm they are configured correctly. Use the DSTAT command.

:DSTAT ALL

Sample output

LDEV-TYPESTATUSVOLUME (VOLUME SET - GEN)
--------- -------------- 
-----------------------------
1- 022040MASTERMEMBER1(MPEXL_SYSTEM_VOLUME_SET-0)
2- 
022040MEMBERMEMBER2(MPEXL_SYSTEM_VOLUME_SET-0)

Checking Volumes completed. Go to the next section on your checklist.
