Manual Upgrade IBM Spectrum Protect 7.1.x to 8.1.x

Image
I'm ended up in a situations where a IBM Spectrum Protect (ISP) server was lock down with limitation who is allowed to login over SSH. The main reason of this is because the server was connected to a Linux based LDAP environment after the installation of ISP was done. So now did we end up in a situation where we not where able to let the local ISP user account couldn't ssh to itself. And because we couldn't ssh even though localhost to our ISP user (let's call it tsminst1). And I guess I'm not alone with this issue so I guess this could be a create blog post for my Spectrum Protect / TSM friends. First of all if you are using SuSE Linux Enterprise Server 11 you most run minimum SLES 11 Service Pack 4. Here is a quick and dirty how to upgrade your SLES 11 to SP4.

I have now heard twice where end-users of GPFS heard it isn't possible to upgrade from GPFS 3.4 filesystem to Spectrum Scale 4.x without to shut down the entire cluster. This is not true and I will now show it for you how easy it is and how it's works.  I want with today's topic explain how easy it is to upgrade a GPFS 3.4 filesystem to Spectrum Scale 4.1.1 without to shut down the cluster. This how my test system looks like and see the time stamp when I start with my upgrade.

And here is a little how to how to move a filesystem from one disk to another. Basic overview ·         Create the new disks in Linux ·         Create a NSD on the new disks ·         Add the new NSD to the file system ·         Remove the old NSDs and let Spectrum Scale to migrate the data automatic. ·         Delete the NSDs ·         Delete the Disks in Linux So let's start with Scanning the SCSI bus for new Disks on all NSD Servers [root@server01~] echo "- - -" > /sys/class/scsi_host/hostX/scan    Replace the X with the correct SCSI Host adapter.
