ML 150 SCSI RAID - expand array

Hi,

In my ML150 with Adaptec 2120S SCSI RAID adpater, I have a RAID 5 array with 5x 136 GB disks.

I added another 136 GB disk and it is at the "ready" state in Storage Manager.

When I try to expand the arrray to use this new disk I get the following error message:

Unable to start the reconfiguration of logical drive : controler 1, logical drive 1 ("ARRAY1"). Error code : [DETAILS: The reconfigure operation failed. RC:-5 API:0x143 IOCTL:0x0]

Any ideas ?

Hi,

Have you tried expanding the array using the Adaptec BIOS config (F8) at power on?

This may work better if there are locks on the logical drive while in Windows - just a thought.

The "expand array" feature is available in controllers that have BBWC (battery back-up Write Cache). The cache memory is needed to save each 5-disk stripe and rewrite it as a 6-disk stripe. Does your controller have this feature and is the battery fully charged?
