Seagate SAS faillure

Hi

Today I got a Seagate SAS part from a RAID 1, that failled.
I don't have any tools to check it, besides the SCSI card.
Can I work with it by terminal?
The HDD just stopped being detected. No bad noises, or power faillure.
I will post the full model here later.
Thanks

With SAS drives, I tend to find 1 of 2 issues:

1. Fatal head crash
2. Bad sectors

I can't say that I have encountered a single case where it was a firmware issue. That said, it is bound to happen when we encountered SAS drives with damaged translators. But certainly not enough to justify the expense of PC3K SAS/SCSI.

With Seagate SCSI drives, I've just used PLSCSI to fix translator issues. Unfortunately, I don't even know if PLSCSI could be used with SAS drives too.

Hello,
if drive is from RAID 1(mirror), then user just need to replace faulty drive.
Could you write more details
With SCSI card, you will not be able to do anything. Buy SAS card

Sorry, my bad.
It's Raid 0. I wish it was Raid 1....

The Drive is a Cheetah ST3146855SS.
Thanks

Theoretically SAS is essentially SCSI, so plscsi should work for it. But I don't know if there are any SAS cards with a DOS driver which it would recognize.

HI Jared

Thanks for the input.

But plscsi works as terminal? You can send commands?
Thanks

Plscsi allows you to send direct SCSI commands to the drive. Including the command to regenerate the translator. No need for a com connection at all. I've never done it with an SAS drive though.
