Is it normal for my HD?

[Fragon]

Some information for this HD please see the attached .txt file!
The strange HD is c2t0d0 (disk 4). It's a hot-swap disk. When I insert this HD into the box, it shows "claimed" in "ioscan -fnCdisk", and just one or more hours later, it become "NO_HW" for "ioscan -fnCdisk".
Then I pull out this HD and insert it again, the OS shows "claimed" again. And later it become "NO_HW" for "ioscan -fnCdisk".
It seems that "vgdisplay & diskinfo" will show error message but I'm really amazing that "sar" work fine!
Any ideas?

Thanks a lot!

No that is not normal.

That disk has failed or can not be put into service.

dmesg should confirm this.

If you are running ems, it should have emailed root a warning as well.

If its a hotswap you might try removing and reinserting the drive.

You might try increasing the timeout on the device, but I pretty much think its dead. It could be the drive cage or cable, but is most likely the drive itself.

I suggest you runing "dd" to test the drive first.

And you may try to remove and readd the disk's definition from the kernel and see if diskinfo works:

# rmsf -H
# ioscan -fnCdisk
# insf -eH

==============================================

I think it is the disk's problem!
Thank you!
