Changing a Partitioned ACS to an Un-partitioned ACS

1. Optionally, eject cartridges from the partition(s) managed by ACSLS.

   If ACSLS will not be managing the non-partitioned library, you may want to eject cartridges from the partition(s) managed by ACSLS. This enables you to enter them into other ACS(s) that ACSLS manages.

   You can use the ejecting.sh utility for ejecting multiple cartridges.

2. Quiesce the library before re-partitioning it, and vary the ACS(s) and port(s) offline.
3. Re-partition the library using the SL Console.

   The following then occurs after you press Apply. The library:

   • Rejects any new requests from ACSLS.

   • Drops all host connections.

   • Applies partitioning changes.

   • Accepts new host connections.

4. Reconfigure ACSLS to change the ACS to an un-partitioned library or to remove this ACS (partition) from its configuration.

   Because the library was changed from partitioned to un-partitioned, ACSLS cannot reconnect to the library. In order to reconnect, follow the procedure below:

   1. Bring down ACSLS: acsss disable
   2. Run acsss_config to configure the ACS.

      Reply n (no) when asked if the ACS is a partitioned library. See Setting CSI Tuning Variables for more information.

5. Start ACSLS with the new configuration: acsss enable.
6. Vary the port(s) and ACSs online.
