NetBackup 22.214.171.124 upgrade - slow backup for SAN disks
We've just upgraded one of our solutions to NetBackup 126.96.36.199 and since have had slow throughput on backups for servers that have SAN attached drives (does not appear to affect local disks). I've adjusted the buffers, patched the clients to the same version and performed all sorts of checks but cant figure where to look next...
Can anyone make a suggestion please?
Master with 5x media servers four of them having disk staging areas (all 2003 media servers have been upgraded to 188.8.131.52, the 2008 media server is 7.5).
