There is also another possible scenario:

1. Do a full backup of DATA for safety.
2. Brake the mirror and swap the first 36GB drive with a 72GB drive
3. don't remirror but create a new volume on the 72GB drive called 
NEW_DATA. 

4. Backup DATA and restore to DATA_NEW. (To minimize downtime 
you can first do a full backup/restore during a slow time and then do an 
incremental backup/restore after kicking out everyone the system). 
ltenatively you can use the Novell Consolidation Utility to copy one 
volume to another and keep all trustee info.

5 Dismount DATA volume and rename NEW_DATA on the 72GB to 
DATA.  

4. Remove second 36 GB drive and add the second 76GB drive and 
remirror.   

This way you don't need Portlock or ServerMagic to expand the 
volumes and you also skip one of the two remirroring steps.

Subject: Data Volume size upgrade

I have a Dell PowerEdge 2550 server with two volumes, SYS and 
DATA. (This
server has only four hot swap drive bays)

The HardWare level mirroring consists of two drives for the SYS 
volume and also two 36GB drives for the DATA volume.  

I need to increase the DATA volume to a 72GB mirrored volumes with 
minimal down time.  

I was hoping to take server down, pull a mirrored 36GB DATA volume 
drive out and replace with a 72GB. Power up server and run the 
Perc3/Di config utility. Add this drive to missing mirror set. Allow this to 
get mirrored.  

In a day or two, take down the server and replace the second 36GB 
drive with a 72GB drive. Power up server and run the Perc3/Di config 
utility. Allow it to mirror. Check and test the server in another day or so 
by doing a reboot and confirm that it's ok.  

Next the two options would be:

1. to create a second NetWare partition for the remainder of the 72GB 
mirrored drive set and then add that space to the existing DATA 
volume. (this would mean having two NetWare Partitions on a single 
drive, which would mean having a DATA volume spanning two 
NetWare partitions) How does the FAT and the DET work in a situation 
such as this? Does each partition have it's own set? Would this benefit 
access time? (or am I flirting with possible disaster)  

2. Use Portlock or Server Magic to expand the original NetWare 
partition to the full 72GB size. (Does Portlock and Server Magic 
expand the volume at the same time or separately?  

P.S. Any recommendations for what would be the  product of choice?

Thanks in Advance!
