How to delete a logical drive on a PERC2/DC ?
Hello all.
I'm running a PowerEdge 2400 with PERC2/DC (firmware 1.01) under FreeBSD 5.
I currently have four HD in it, setup as two logical drives:
. a pair of 9GB HD as logical drive 1, RAID 1 (several partitions)
. a pair of 36GB HD as logical drive 2, RAID 1 (one partition)
One of my 36GB seems dead, amber LED and alarm sound.
I bought a pair of 73GB HD to replace the pair of 36GB and extand my logical drive.
This is the scenario I wanted to play:
. backup the data (of course)
. umount the partition that points to the logical drive 2
. delete logical drive 2
. remove the pair of old HD
. put the pair of new HD
. create a new logical drive 2
. create the partition and format it
. restore the data
Unfortunatly I did not manage (AT ALL) to find how to delete the logical drive.
Either from the PERC2/DC bios (at boot) or from the MEGAMGR (quite old) on command line I was NOT able to delete the logical drive.
I find how to delete the whole configuration (also logical drive 1) and read (somewhere I can not find anymore) that if I recreate the logical drive 1 right away data won't be lost but this is something I don't want to try.
I found information on how to do it with the special tools under Windows but this is not an option : http://support.jp.dell.com/docs/stor-sys/dom/marb27/perc.htm
I was not able either to put one 73GB drive instead of the broken 36GB and rebuild the array.
Does anyone here knows how to do it from the BIOS ?
Would an upgrade to firmware 1.06 help ?

PS : I can boot with a live CD under linux if there is a linux tool to do it.

I just found that the last firmware for PERC2/SC included the "delete logical drive" option (missing from previous firmwares) : http://lists.us.dell.com/pipermail/linux-megaraid-devel/2002-January/000177.html
Does anyone knows if this is the same on PERC2/DC ?

David,
I'd suguest trying it and see if you now have the function available.
As far as deleting the configuration, here is how I would aproach that: Before I clear the configuration, I would remove the drives that have the array I want to keep. After clearing the configuration, I then reinstall these drives and the controller will report a NVRAM mismatch, at which time I select to view disk configuration, save the config and exit, vola the array is now array 0. If you need it to be array one, install the drives for the new array first, create that then add the old array, and do the view disk and save... now array 1.
