ok needing some help with an issue, i'm not sure what to do about..
have two hosts with dozen or so vm's running on
san storage already working with both hosts, with multipath.
added a new lun 500gb, can't get it added to host 2.
details of new lun:
pr-al-ovm02 LUN 205 | 205 | Ready | RAID5 | VP 02 | - 500.000
| SP A | PR-AL-LPSOVM2 | 60:06:01:60:7E:A0:21:00:9A:44:A9:12:CA:AA:E4:11 |
hosting server has been rebooted.
here are the commands i have tried so far:
