We want to upgrade a pretty old x86 GPFS/HSM environment what consist GPFS 3.2.1 + TSM 5.5 (RSCT) on three x3650M2 servers with RHEL4 OS. The capacity on tape is quite huge in this particular case.
Based on our investigation the upgrade to version GPFS 3.5, TSM 6.4 and RHEL6 (let say the recent supported versions by 3.5) would take several steps. At least seven, because of the dependencies between the various versions.
Does anybody know a shorter or easier way to deliver this upgrade ?
Thanks in advance !
