SCSI SMART attributes

[fawrell]

Hi.

I just bought 2 new 146GB scsi disks and inserted them to my HP MSA 30. All seems be ok, but one of the disks (SCSI Port 2, Drive ID 5) got some SMART attributes not null and on the other disk (SCSI Port 1, Drive ID 5) they are null. I'm talking about these attributes: Test 2, Test 3, Test 4, Seeks, Re-mapped.

The SMART log from both disks:

My questions are:
1. What is the meaning of those attributes? Means that the disk got some trouble?

2. Is there any guide, that is explaining the meaning of SCSI SMART attributes? I could not find any.


Tnx for answers!

There are SCSI SMART attributes on this page. You'll have to scroll down, there are ATA ones at the top of the page. Looks like 2 deals with write errors, 3 with read errors, and 4 with reverse errors (whatever that means).

Are you using an HP/Compaq SCSI controller? I've had very good luck with their controllers telling me when something is wrong with a drive before the drive has totally dies. I kept having issues with my arrays failing on a Dell PERC controller, but the controller would not consistently report the same drives as bad. I plugged the drives in question into a SmartArray controller, and it became very clear which drives were going bad.

If the SmartArray controller is happy with the drives, I wouldn't worry about them.
