Raid for Redhat
I have an LC2000r with a raid 5 array. I now need to increase the drivespace, I am receiving 3 new hard disks. Is there any software that I can run on the redhat box to allow me to configure the new drives without reboot? Or for that matter is there any sw for configuring the raid either way? or do i have to reboot and run the old ctrl+h(or M i can't remember).
Any suggestions would be greatly appreceiated
Simon

Re: Raid for Redhat
Either way, you want the linux version of the 'megamgr' tool. There was a post here a few weeks ago about the 'dell' tools for the controller management. I beleive those tools should work as well (they don't look for Perc specifically, but the AMI RAID controller chipset which both the Perc and the M/Si series are based upon (except for the 4M)).
They do require a given version of the kernel drivers unfortunately (greater than 0.15 or something), but they are provided with any RH kernel after the 7.1's.
Anyway, I hope this helps you a bit.

Re: Raid for Redhat
I had to downgrade the kernel to 2.4.18-27-7-x before I could get any of the LSI Login Megaraid tools to work.
Check out
http://www.domsch.com/linux/
for info om the Megaraid tools (Dell-specific site, but should work with your RAID controller)
If you are using a different controller, please post the BIOS banner for it so we can better help you.
Thanks.

Re: Raid for Redhat
shove 'em in, config 'em up, mkfs and away you go.
If you want to expand the existing logical array, then you'll have to backup etc. like Bill suggested.
