Disk Administrator Extend Volume Set Issue

[Vivek Desai]

Hello,

I am using HP Netraid assistant Version A 02.02 on a HP Netserver LH3. I had
5 drives set on Channel 0 of the server and format of the
RAID set as RAID 5. On the Netserver I have Windows NT
4.0 installed. When I tried to put in the 6th drive on
Channel 0 The Netraid software succesfully added my 6th
9 gig drive to the raid that is setup. So on the netraid
I see 6 physical drives (all online) set on channel 0 with disk space
of 43370 mb.

In the Disk Administrator utility of Windows NT 4.0 the
structure of the disk is as follows:

C: 1953 MB
E: 15398 MB
E: 8676 MB
E: 8676 MB

In the Disk Administrator all of the drive letters listed
above are on Disk 0, with the C drive as the primary
partition and the E drive as the extended volume set.

When I tried to extend my current volume set to include
the new 9 gig drive I installed it gives me the following
2 errors

1) The disk containing one of the free spaces you have
chosen is not able to accept any more partitions

The above error shows up when I highlight the current
extended volume set and the new physical drive, right
click on them and select Extend Volume Set..

2) No more primary paritions can be created on the disk. A
Disk cannot hold more than 4 partitions (including the
extended partition but not including logical drives)

The above error occurs when I just right click on the
new physical (8676 MB) drive I have installed and click
on either Create.. or Extend Volume Set

My question is why is it happening and what are my
options from hereon. My main goal in doing this is to extend the above mentioned E drive in Windows NT from its current size to 43 gigz(as the disk is almost full) leaving the current data on the Extended Volume Set (E drive)intact.

Thank you all in advance for your help. Hope to hear from
one of you soon. Please let me know if you have any question

Hi,

Often in NT4.0 when you add capacity to an array, disk manager will not be able to use the new capacity without a reboot.

Have you done a reboot? If not reboot the system and retry your task.

This is not a NetRAID issue. I was able to re-create this very easily on a non-NetRAID system (Netserver LC2000 attached to built-in SCSI). Has NT Server 4.0 installed with Spk6a (not a Navigator install, manual with no utility partition). Six hot swap drives.

1. Have one primary partition which is the C: drive.
2. Created one volume set, set drive letter to E:. Committed changes,then formatted to NTFS
3. Extended volume set = now have 2 volume sets, both drive letter E:
4. Extended the volume set again = now have 3 volume sets all designated as the E: drive.
5. Try to extend volume set again...get the same error reported abouve:

"The disk containing one of the free spaces you have chosen is not able to accept any more partitions"

Looks like an NT Disk Administrator limitation.
