$ sudo mpt-status -i 2
ioc0 vol_id 2 type IM, 2 phy, 67 GB, state OPTIMAL, flags ENABLED
ioc0 phy 1 scsi_id 4 FUJITSU  MAY2073RCSUN72G  0401, 68 GB, state
ONLINE, flags NONE
ioc0 phy 0 scsi_id 3 FUJITSU  MAY2073RCSUN72G  0401, 68 GB, state
ONLINE, flags NONE

thanks for all of your help. looks like both disks behind the controller are ok.
