I'm trying to remove an iSCSI host from our HP MSA P2000 SAN. I'm getting an error that because it is still "discovered", it cannot be removed. Is there a way on the MSA to "refresh" the discovery or do I actually need to restart the MSA to initiate a host scan ? I have our main storage on there connected to another host, so I'd like to avoid restarting it if possible.
Second quick question. On one of our RAID 5 volumes, one of the disks shows as "3.0" Transfer rate, while the remainder show as "6.0". In theory the disks are identical, but maybe not. Is this single spindle in my RAID 5 slowing things down ? I do have spare 6.0Gb disks. Can I just yank it and replace it with a 6 ? I've got 4 disks total on that RAID 5 volume.
