The two disks have been replaced and we restored the the pool.

After one month, i got firmware error below and we can't connect to the server throught ssh:
[ Apr 3 10:00:24 sdp032 scsi: WARNING: /ssm@0,0/pci@18,700000/scsi@2 (mpt0):

I upgrade the server's firmware to the latest version 5.20.16

5 days later, we got same firmware error and we replace again the two disks and the system has been restored but the problem was not solve .

Now we have again the same disks error again.
