Extending Disk Array Win2K Server


I have a problem. I cannot extend the logical drive after adding 3 extra HDD's into the external drive enclosure, making a total of 9 disks. I downloaded the latest ACU for Win2K, v2.90.65. However, when I went through the GUI wizard it said "extension is not currently supported on Win2K. Do not attempt to use this feature as data loss could occur". Naturally I cancelled out of this option and instead created a 2nd logical drive using the sam ACU tool without any warning messages. This is not ideal. Is there a way for me to extend my original RAID5 logical drive to include the extra HDD's? I can always delete the 2nd logical drive. The Smart Array Controller is a 5300 installed into a Compaq Proliant DL380 running Win2K Server as the operating system.

Re: Extending Disk Array Win2K Server

Once you have added the disks in to the array go to the CMD prompt and type DISKPART.

Do a LIS VOL to see your volumes.
Then SEL VOL x (where x is the volume number you wish to extend)
Finally type EXTEND and DISKPART will extend this volume for you.

Good luck,

Yes, DISKPART will work for you, delete that logical drive you made first though.
Or you can use Disk Manager to join the 2 partitions together into a single OS logical or extend the current logical.

Re: Extending Disk Array Win2K Server


Thanks for the info. I'll give it a go this weekend after backing up the data. Just to clarify, can I go into disk management, delete the new parition I created from the 3 new disks I put into the array; (It is a Basic type), then run the diskpart commands to extend the original partition to encompass the space of the new disks?

(Do I need to delete the logical drive using the ACU tool?)
