expanding hotplug drives

[ataylor44]

OK guys I'm the one that drives as running out of room on the raid 1+0 18 gig drives.I got the new 36 gig drives and with your help swapped the drives out and there up and running fine the problem is one of the members here said to use a utility to expand the drives from 18 gig to the new size of 36 gig with partition magic.I did use partition magic v.4 and it did not see the new space.We have tried server magic with a netware box and moved the partition the wrong way and ended up using a bootup disk to boot up the netware box so I'm not to sure about using server magic on the NT 4.0 box.Is there another utility I could use to expand the drives.Thanks in advance.

I've added larger disks to compaq servers before, and in the case of adding new disks, used the smart start CD to expand the array.
When we've replaced the old disks with larger ones we've built the server again and restored the data.
Have you pulled the disks one by one and added a new one each time?

Yes I have already done that.When you say rebuilding the server you had to wipe the drive clean creating the new array size and then restoring the data from tape backup?Thanks

It was a netware server. We backed it up to DLT, removed the disks and inserted the new ones. Then re-installed netware, and restored the data. I'm afraid I don't have much experience with this in NT.

In NetWare, it's easier than that. Once you have pulled the old drives (individually) and replaced with the bigger drives, you run CPQONLIN.NLM and add the additional space as another logical volume.

I guess with NT you'd replace the drives individually, go into the Array Configuration Utility, and do something similar. You would still have to use PQMAGIC to stretch your NT partition though but at least it will see the extra space then. -----------------------------------------------------

Having done this recently, I found the easiest method is simply to backup the Entire machine to tape drive, reinstall a basic OS and restore the backup.
