Yes No
↓ You cannot power off the tower at this time. The SPCN controlling
system must be running OS/400 or at SST/DST to power off the
tower. Correct that problem first, then perform this procedure again.
This ends the procedure.
5. Work with the customer to switch ownership of the tower’s HSL I/O bridge
resource to the tower’s SPCN controlling system. To do this use the
OptiConnect for OS/400 information.
Were you able to switch ownership of the tower’s HSL I/O bridge resource to
the tower’s SPCN controlling system using the OptiConnect for OS/400
information?
No Yes
↓ Go to step 7 of this procedure.
6. Working with the customer, use Hardware Service Manager (HSM) to switch
ownership of the tower’s switchable resources to the tower’s SPCN (Power)
controlling system. To do this use the ″Service Reference Procedures″ in the
iSeries Service Functions information.
Were you able to switch ownership of the tower’s switchable resources to the
tower’s SPCN (Power) controlling system using the ″Service Reference
Procedures″ in the iSeries Service Functions information?
Yes No
↓ Contact your next level of support.
This ends the procedure.
7. Perform this procedure from the SPCN controlling system’s Primary partition
until you are directed to do otherwise.
Work with the customer to end the Cluster Resource Group (CRG) containing
DASD units configured as independent ASPs (IASP) under the tower’s HSL
I/O Bridge resource. Refer to the OptiConnect for OS/400 information.
Were you able to end the CRG using the OptiConnect for OS/400 information?
No Yes
↓ Go to step 9 of this procedure.
8. Working with the customer, use Hardware Service Manager to switch the
towers mode to Private using the ″Service Reference Procedures″ in the iSeries
Service Functions information.
Were you able to to switch the towers mode to Private using the ″Service
Reference Procedures″ in the iSeries Service Functions information?
Yes No
↓ Contact your next level of support.
This ends the procedure.
9. Check to see that no other towers, controlled by this system’s SPCN, are
powered off at this time. Perform “BUS PIP HSL-05” on page 305, then return
here and continue with the next step of this procedure.
Attention: During this procedure only one tower connected to this system
can be powered off! You must not have more than one tower powered off at
any given time during this service action!
10. Using table “Appendix F. HSL Loop Configuration and Status Form” on
page 963, identify the tower that you are working on. Look at the ″Link
