Checking Hardware Error

[C_V]

Hey i guys i received this kind of error on our logs:

May 18 06:58:39 server1 scsi: [ID 107833 kern.warning] WARNING: /pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cfb53a97,0 (ssd1):

I tried checking the disk via iostat and here is its output:

c1t0d0 Soft Errors: 0 Hard Errors: 2 Transport Errors: 0
Vendor: SEAGATE Product: ST447705FSUN36G Revision: 0638 Serial No: 0353P22S7Q
Size: 36.42GB <36418595328 bytes>
Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0
Illegal Request: 0 Predictive Failure Analysis: 0

- I always check at "Hard Errors: 2" if this has a low value then i conclude that the disk is ok.

- Is this enough to say that disk is ok or is there anything else that can be done to check the disk?

- Also the WARNING given is that a big problem.

If you have access then do physical inspection, look for orange/yellow blinking lights.

or do a dd

dd if=/dev/c#t#d# of=/dev/null bs=1024 count=1000

If the disk is very critical, then do the dd for the whole disk ( may take time).

hi,

check the disk with mstm utility, if there are some errors contact HP to replace the HDD.

Hello,

check your LVM configuration and make sure the logical volume that lies on this disk is protected with mirroring.

However, you should be thinking of replacement anyway, this may be an early indication of eventual disk failure.
