I'm trying to tune our mount retension settings on our device classes. Currently, we have it set to 3 min for our 3590 drives. I'm not finding much info on how to tell if our 3 min period is too long or too short.
1st try . . . . I sorted the mount messages (anr8337i)in a actlog listing of 24 hours by volume/date/time and looked for multiple mounts of the same volume that were real close together in time and on the same drive. I found just a couple. 2nd try . . . I counted the number of the following messages in a actlog listing for 24 hours: anr8337i - mounted vol msgs = 415 anr8325i - dismounting with expired mount retension = 230 anr8468i - dismounted vol msgs = 415 This might indicate we had 185 instances of mount retension being useful. But . . . I'm not sure of is whether a mount satisfied by a already mounted tape even has a mount msg in the log???? I'm also not sure whether a tape always waits for the mount retension period to be dismounted, or, whether it can be immediately dismounted if there are pending mount requests for other volumes. I looked in the manuals and online but didn't find much that helped. Any thoughts on how to tune mount retension are appreciated!!!!
