SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

system automatically adds an installed adapter back to the system configuration database in any
of these cases:
• You remove the adapter and then insert it back into the slot.
• You restart the system.
• You power off and on the adapter or its enclosure.
• Example
1. Identify all the devices currently using the adapter:
-> STATUS $ZZSTO.#SNDA.GRP-11.MOD-1.SLOT-51, DETAIL
See “Example of a Detailed INFO SNDA ADAPTER Report” (page 156).
2. Stop each of the devices or device paths that use the adapter.
3. If any disks belong to a storage pool, you get an error message. You must first remove them
from the pool. (See the Storage Management Foundation User’s Guide.)
4. Delete all paths connected to this adapter.
5. Physically remove the adapter.
6. Delete the adapter from the system configuration database:
-> DELETE $ZZSTO.#SNDA.GRP-11.MOD-1.SLOT-51
Managing a Storage Adapter
Management tasks for storage adapters include:
• “Troubleshooting Adapter Installation” (page 167)
• “Changing the Active Path for a Storage Adapter” (page 167)
Troubleshooting Adapter Installation
If the slot that you want to install an adapter in was previously configured for another adapter,
you get an EMS message (storage message 1041) and the adapter is not configured. To remove
the previous configuration:
1. Find out what storage or LAN adapter is currently configured for that slot:
-> INFO ADAPTER $*.*
2. If that slot is configured for a LAN adapter, stop and delete all subordinate objects like LIFs
and PIFs.
3. Delete the adapter:
-> DELETE ADAPTER $ZZSTO.#type.GRP-n.MOD-1.SLOT-n
-> DELETE ADAPTER $ZZLAN.#type.GRP-n.MOD-1.SLOT-n
4. Physically install the new adapter.
5. Verify the adapter is available and ready to use:
-> STATUS ADAPTER $ZZSTO.#type
Changing the Active Path for a Storage Adapter
The “SWITCH ADAPTER Command” (page 294) moves all device paths from and to a SAC on an
adapter.
Use this command before replacing a device that contains a storage adapter and dual paths.
