Comment:

El disco no responde a los comando de sg3 , y esto queda reflejado en el iostat aumentando el numero de errores de transporte:

root@seal:~# iostat -En|grep c2t5000CCA369C508E5d0
c2t5000CCA369C508E5d0 Soft Errors: 0 Hard Errors: 13 Transport Errors: 27

root@seal:~# sg_inq  -u /dev/rdsk/c2t5000CCA369C508E5d0
inquiry: pass through os error: I/O error
    inquiry: failed, res=-1

root@seal:~# sg_inq  /dev/rdsk/c2t5000CCA369C508E5d0
SCSI INQUIRY failed on /dev/rdsk/c2t5000CCA369C508E5d0, res=-1

root@seal:~# iostat -En|grep c2t5000CCA369C508E5d0
c2t5000CCA369C508E5d0 Soft Errors: 0 Hard Errors: 13 Transport Errors: 29

Tampoco funciona el commando smartctl sobre este dispositivo:

root@seal:~# smartctl -a -d sat /dev/rdsk/c2t5000CCA369C508E5d0
smartctl 6.0 2012-10-10 r3643 [i386-pc-solaris2.11] (local build)
