Expanding RAID

Hi, this is just a safty check before i try anything.

it is a live server , and very important. do intend to move it on to a better box, but for now have to make do with making the hardrive bigger.

compaq proliant 3000 standard compaq array,

raid 5

all partions on the raid no seperate system array.  c: d: e: f:   comprising 6 9.6gig drives

question is how do i expand the array (if at all) . I dont have the luxury or rebuilding this one. just need to make one of the partions bigger

NT 4 sp6a

i don't think that it is possible to add a disc to the array without having to rebuild since in the bios, the config is set for the current setting....

you can change a disc (that is HOT swap) but not adding one

You can expand the array through the ACU after adding another disk no problem, I would recommend putting the latest flash on the RAID controller first although the data loss during on-the-fly problem is only with win2k and above dynamic disks. The problem you have though is making one of the partitions bigger, partition/server magic and similar tools don't work online.

With NT4 the only way to extend a raid array is to break it, then re-create it.  But you would lose all the data.

Sorry :-(

It isn't NT that is expanding the array, it is the RAID contoller (probably a smart 2DH if it's a proliant 3000) and it can expand the array while NT4 or Windows2000 or Netware are running without the OS knowing about it. The only problem is that after expansion under the OS you just see the same original partitions on a bigger drive with a spare bit of unused disk (9GB in this case) on the end.

Paulryan, not true at all.


You can expand the array using the array config utility and then create a volume set using the disk administrator. Remember you can't create volume sets for the c: partition.

Once the array has expanded, reboot the server and go into the disk admin, you should see the free space. If you don't, you need to look at this q article to turn autocheck on so the drive resizes after the reboot.

Thanks Mustangbrad, I completely forgot he could use a volume set after the expansion instead of repartitioning.
