Cause

These symptoms have been seen following a power cycle or reboot of the SL8500 when the ACSLS server commands to offline the CAP or issue offline ACS commands had not have been issued first.
The “Reserver” field showing “Default” suggests that the host (ACSLS) has not picked up the CAP after the SL8500 came back up. ACSLS needs to reserve it before any production is possible.

Solution

Ensure whenever possible that if an SL8500 is to go offline or power down that the ACS or relevant part of the ACS is taken offline in ACSLS first, as this avoids the issue.

Relief/Workaround
ACSLS software support recommends that if this has occurred that the entire SL8500 is taken offline and back online to ensure that all library components are checked and synchronized.
Offline ACS 0
Online ACS 0
However with the older ACSLS software 7.1 this does not recover the CAP and the following procedure was proven to work by taking only the CAP offline and hence avoids taking the rest of the ACS offline.
This issue has not been seen on the latest ACSLS software 7.3.
 
Vary Off the CAP in SLConsole
Vary On the CAP in SLConsole
Vary Off CAP in ACSLS
Vary CAP mode to manual in ACSLS         Set CAP mode Manual 2.1.0
Set CAP to automatic in ACSLS                 Set CAP mode automatic 2.1.0
Vary CAP online
 
This works every time, it appears the change in ACSLS settings for the CAP mode cause it to correctly acquire the CAP reserve on the SL8500.
