There's a red light on of the drive bays. The promise utility says the drive is dead. Can i just replace the drive? Should it be exact the same type?

Hi Sander,

If the Pegasus has the default configuration, it's a RAID5 volume and if you replace the failed drive with the same size drive or larger an auto-rebuild should start.

There is a new issue in that some new drives show as passthru, if you see this in Promise Utility change the drive to unconfigured then make it a spare and an auto-rebuild should start.

For Pegasus32 the drives are probably still being manufactured, so replacing with the same drive is best. While any drive of the same size can be used, staying with the same manufacturer will help as the drives will have similar characteristics.

How/where do I change the drive from passthrough to unconfigured?

 

I have the same issue and not getting a rebuild

Hi Lars,

The simplest way is with the CLI. Open a terminal and enter promiseutil, this will start the CLI if you have the Promise Utility installed. The Promise Utility is needed for this, so if it's not installed, please install it.

For example, in the case below PD1 has been replaced with a passthru drive. The phydrv command shows the state of the drives. The CLI commands are bolded.

The steps are

1. Change PD1 from passthru to unconfigured.

2. Make PD1 a spare.

After PD1 is made a spare, the controller will start a rebuild on it. It takes a few seconds.

Works like a charm. Thanks.

This is not in the manual, AFAIK.
