Can this be one just one host at a time?


We did it one host at a time, painful becasue each host has to be powered off. over 140 hosts!

IT might be worth my while trying to get HP to confirm this for me too ... seeing as we have a bunch of persona changes to do!


Page 7 of the VMware best practices guide states this.

Does it matter if you have multiple LUN's exported to a hostset and you only change the persona of 1 host?

I don't believe so, as you could have 5 esx servers and a windows server in a host set, the windows server being the backup server.

Just to make sure I will rephrase my question.
Does it matter if 1 LUN is exported to 2 different persona ESXI's (the old persona and the new)?

No. We have multiple LUNs presented to a host set and we did a rolling change of the persona, putting one host at a time in maintenance mode, shutting it down, switching the person and powering it back up, the moving on to next host in the esxi cluster. Just time consuming.

Indeed, when you are hp changing host personas, you aren't changing the luns in any way, just the way that host handles luns and paths etc.

It's not like a netapp where we have hosts set with a certain os type and also choose the os for the lun at creation.
