I have had 2 drives go down at the same time. Can I rebuild them? Do I do it one drive at a time or both together?

Hi Gav,

It's more complicated than that. You can't do a rebuild if it's the default RAID5 as it can only tolerate 1 drive offline.

Please save a service report, zip it and attach it to your post.

Here's a knowledge base article on saving a service report.

This procedure is for using the Promise Utility to save a service report, the procedure is the same for all Pegasus models.

Thanks R P

I've done what you asked....Now I know I might not be the brightest bulb on the box, but how do you add a zip file? There seems to be only photo files allowed.

Hahaha flag that... I've just seen the attach button after I posted the last post.  

FYI. I have the PROMISE Utility Pro. The older utility was on an old computer that I no longer have. the attachement is an .html file.

Hi Gav,

Thanks, the Pegasus Service Report is an html file, this is what was wanted.

You have a RAID 0, you can't do any rebuilds.

[Logdrv Info]

===============================================================================
LdId Alias       OpStatus      Capacity  Stripe RAID    CachePolicy     SYNCed
===============================================================================
0                Offline       12TB      128KB  RAID0   RAhead/WThru    Yes

You can't replace any of the drives in the array. All you can do is bring the offline drives online and hope they stay online.

Both PD4 and PD5 and bad. Here are the CLI commands to bring the drives online.

To open the CLI, open a terminal and enter 'promiseutil'. The commands are...

phydrv -a online -p 4
phydrv -a online -p 5

After bringing PD4 and PD5 online I would suggest you copy off any critical data and anything you want to keep. Then replace PD4 and PD5 and create a new RAID5 array. Update this forum post if you need help with this.

These drives will probably go offline in a short timeframe, you can force them online again if necessary.
