The tape driver does the switching from active to standby path. Tsm doesn't know anything about the paths it just sees the device /dev/rmt*
I have 4 3590E driver with dual fiber attachments. Although you must be using IBM SAN adapters to user this functionality or the aix server will see an rmt device for each path. I use cambex adapters since we are use and hp san network. My aix server sees one drive with 2 paths as 2 separate devices. So I wrote a script to that monitors the path and if it fails to go into tsm and change the device to the path of the other rmt device.

We are in the process of formulating an AIX environment instead of our current MVS TSM environment. We would have 2 TSM servers (one being the library manager) with 2 directors, 8 lan-free clients and 24 tape drives, which we hope to share between the 2 TSM servers. We would like to have 2 fibre interfaces per drive in order to eliminate a single point of failure. My question is, how does TSM know which path it is using to the drive and how does it know that one of the paths to an individual drive is already in use? Is there software out there to manage this or is it done through the hardware configuration? If anyone has any suggestions I would appreciate it! Thanks! *************************************************************** Joni Moyer Highmark Storage Systems Work:(717)302-6603 **New as of 11/1/03 Fax:(717)302-5974 [EMAIL PROTECTED] *************************************************************** ***************************EMAIL DISCLAIMER*************************** This email and any files transmitted with it may be confidential and are intended solely for the use of th individual or entity to whom they are addressed.
