MSL5052 keeps going to "sleep"
We have a dedicated backup SAN with a fibre-attached MSL5052 (using an E1200), and 2GB Brocade-based switches, approx. 20 servers are also attached to the SAN. HBA's are a mix of QLA2310's and Compaq/Emulex cards.
We use Syncsort Backup Express 2.15D, however two or three times a week the library goes into a state of "Initialisation", I get in in the morning, reboot the library via the web interface and all is fine till it happens again.
I have gone through each piece of hardware - Library, drives, E1200, switches and HBA's and they are all at the latest frmware, this hardware has been in approx. 2 years now, before this would only happen maybe once a month but now its much more frequent. Any suggestions?

Re: MSL5052 keeps going to "sleep"
I found the problem - we had disabled the Fibre Agent from the Insight Manager agents on each server on the fibre, but our Netware servers had CPQFCASA.NLM loaded - also a fibre agent, I unloaded and deleted this NLM from each server and the library ahs not gone to sleep for over a week.
My guess is that the agents stay active even afer the server has finished its backup and released the tape drive, the next server tries to acquire the drive and this causes the library to re-initialise

Re: MSL5052 keeps going to "sleep"
In a Windows environment there is some known sw that cause this problem, onw is in fact the FC insight agent with some versions of the Agent, another is RSM, the services of windows, and especialy with W2003, due to a bug of windows, it may start even if the services is disabled in Computer management
Remember that these sw could also be on the same server that the backup application and cause the same problem. Also valid for a direct attached configuration.
