Solution 1487764.1 : SL8500 - Library Not Online After ACSLS Restart

Applies to:

Sun StorageTek SL8500 Modular Library System - Version Not Applicable and later
Sun StorageTek Auto Cartridge Sys Lib SW (ACSLS) - Version 7.3 and later
Information in this document applies to any platform.

Symptoms

Library not online after ACSLS restart.

Cause

installing new firmware in the SL8500 or shutting down ACSLS for maintenance.

Solution

It is recommended that ACSLS issue a Vary Offline command to each ACS. This is particularly important if the ACSLS server is going to be shutting down. If not, it is possible that when restarting ACSLS you may encounter a problem getting the LSMs back online. Should this happen, reference KB 1360720.1 ACSLS - re_vary_lsm: Vary failed, message STATUS_NOT READY.

The issue can be verified if a message like "va_lsm_state:st_ptp_status: LSM 0, 3 type changed from 8500 to 8509; LSM remains offline" is in the acsss_event.log. The workaround is to perform an acsss_config in ACSLS 7.3 or modify the "desired state" attribute in the ACSLS 8.x database to "offline" as instructed in the KB entry.

Action - Issue "vary acs x offline" prior to rebooting a library with new code activated (as instructed in the code release notes) or prior to shutting down the ACSLS software to avoid this exposure.
