Resize raid array
Unfortunately, not only is the whole array in use by the compaq hardware, but it's got Windows 2000 on it with one big NTFS partition. This is a critical system, so I can't just back it up, rebuild the array and restore from tape.
However, I'm not aware of any way to resize a compaq array w/out destroying the logical drive and all data on it. At least not without a spare set of drives to replace it with.
Has anyone managed an online migration such as this? What tools did you use?

Re: Resize raid array
You could attach another array (is this FC or SCSI?, set up array, logical drive and partition. Copy your data over, delete old array/LD/partition, then reletter your new array. You can then remove the old array and re-deploy the drives. This would involve minimal downtime, a matter of minutes. How active is the data? If really active, you will lose some delta during the copy, unless you have replication software.

Re: Resize raid array
The question then is, can you shrink the Compaq array's LUN. I know you can grow LUNs, but I'm not sure you can shrink them without deleting them and re-creating.

Re: Resize raid array
Just not sure if I can resize the logical partition that's been created out of the drives w/out destroying it. Grow yes, shrink...it doesn't look like it.
