scanning for bad blocks

[fordian]

Hi,

Is there a tool to scan luns from ESX console 3.x to find bad blocks ?

Tthank you

I do not believe there is a utility available form SC to scan Datastores for underlying bad blocks. You might want to check your SAN provider, or on board raid controller for local storage, for this functionality.

Thank you.

In most cases, the storage is protected by a RAID controller, which should be able to do single 'bad-block repairs' transparently.

Would a simple read-check be sufficient?

. esxcfg-vmhbadevs

vmhba0:0:0 /dev/cciss/c0d0

vmhba0:1:0 /dev/cciss/c0d1

vmhba0:2:0 /dev/cciss/c0d2

vmhba2:0:1 /dev/sda

vmhba2:0:2 /dev/sdb

vmhba2:0:3 /dev/sdc

.

. dd if=/dev/sda of=/dev/nul
