Reclaim IOP Cache Storage
1. If you are not already using dedicated service tools, perform an IPL to DST (see
“Dedicated Service Tools (DST)” in the
iSeries Service Functions information). If
you cannot perform a type A or B IPL, perform a type D IPL from removable
media.
2. Reclaim the cache storage by doing the following:
Did you get to DST with a Type D IPL?
Yes No
↓
Go to step 2d of this procedure.
a.
Select the Work with disk units option.
b. Select the Reclaim IOP cache storage option.
c. Follow the on-line instructions to reclaim cache storage. The system will
Automatically perform an IPL to a Disk Configuration Warning Report
screen. Take the option to display the report. Because the Reclaim Cache
Storage was selected after a D-IPL, the system will now require another
Reclaim Cache Storage to be performed.
d. Select the Work with disk units option.
e. Select the Work with disk unit recovery option.
f.
Select the Reclaim IOP Cache Storage option.
g. Follow the on-line instructions to reclaim cache storage. Depending on the
reason for performing the Reclaim IOP Cache procedure, there may be a
message requiring the ASP be cleared before performing this option, or a
message stating the number of lost sectors.
Note: If there are lost sectors, some objects may be damaged. The customer
may have to load the damaged objects again. (see the
Backup and
Recovery for more information.)
Note: When the IOP performs a Reset/Reload, if there is a storage IOA
attached that is running the local load source, Cxxx xxxx codes will
be displayed in the system control panel. The DST console may then
have a blank screen with 01B displayed on the system control panel
for up to 15 minutes before it is restored.
This ends the procedure.
