Hi Everyone, I'm wondering how others handle lining up tape paths of multiple TSM servers in a library sharing environment.
We have a TSM library sharing environment across our TSM instances for sharing our two 3584 libraries. One 3584 at each datacenter with a dedicate TSm instance for the library manager. Currently I have a script that crawls through all TSM instances, gets the wwn of each rmt device (lsattr -El rmtX), lines up all the wwn/rmt# for a drive and creates TSM path commands. Kind of brute force, but has worked very well over the years. I can create path cmds for everything in about 15m. But, this means that a particular drive can have many different rmtX devices across our TSM servers. A while ago I learned that you can rename a rmtX device (rendev -l rmtX -n rmtY). I've been thinking about a new system where I rename the rmtX devices on each AIX lpar to a common name. For example: If a particular lpar has rmt1 which is our "a" 3584, and the drive is frame 1 drive 1, then I could call it rmta11. There is atape involved with multi paths, so there would also be -pri and -alt versions of the name somehow. So this particular drive would have the same AIX device name across all AIX lpars. So, I'm curious . . . What do you do to line up rmt devices? Do you rename rmt devices to a common name, or, line up the many different rmt devices? If you rename rmt devices, what issues/problems have you worked through?
