I wanted to know if someone can help me to know the meaning of these messages.

Thank's

It means that one of yours disks is dead or dying.

[Sunny Jaisinghani]

How I can identify wich disk is dying?

[Berd]

Run a ioscan against your disks to see if any are at fault. ioscan -fnC disk

Regards,
Berd

[James George_1]

To fine your disk :

# ll /dev/* | grep 0x160000

and also do
# ioscan -fnC disk | grep NO_HW
