Folks,
In MDSM I noticed that the Virtual Disk our Exchange Server is using for our e-mail database is running in RAID 0!! (This was setup before I took over). There are two RAID Controllers and the Exchange Server is using Controller 0, Virtual Disk "Mail", and is using 3 Physical Disks out of the 14 present in the enclosure.
The second RAID Controller (1) has since been disconnected from it's host File Server (Due to a server upgrade and decommission of the old Host Server). It has the remaining 11 drives still associated to the Virtual Disk "File Server" in a RAID 5 config.
My question is:
(A) can I delete the "File Server" Virtual Disk and Disk Group, (and remove the old File Server Host Object), to free up the 11 Disks and use some to Expand my "Mail" Virtual Disk? Will I also have to change anything on Controller 1 to let Controller 0 'Have' those disks?
(B) Will adding those disks to Expand my "Mail" Virtual Disk re-Initialize it and kill my Exchange Database?? (Common sense tells me 'no', but not taking any chances with my non-redundant e-mail database)
(C) Once I have added the required drives to "Mail" to expand it sufficiently, can I then migrate the drive from RAID 0 to RAID 5? Again with no threat to my database?
(D) Finally, when "Mail' has been successfully expanded and converted to RAID 5, will anything need to be done with the host server, or will the new drive capacity simply just change and show up in Disk Manager?
It appears I can do this all through the MDSM. (Yes?)
Thank you all for your help!! I'm on borrowed time here so any speedy responses are greatly appreciated!
