Before merging both hard disks I saw each of them as a separate SCSI device, at boot time and when the system booted up. After building the RAID1, when the system boots I only see one RAID device recognized, and so do I when linux recognizes it.
[root@lala log]# cat /proc/scsi/dpt_i2o/0 Vendor: DPT Model: 2100S Rev: 320P, scsi 0:
DPT I2O Driver Version: 1.14/1.14:
cmd_per_lun = 210, max_id = 15, max_lun = 7, max_channel = 0 sg_tablesize = 39, irq = 11, OutstandingMsgs = 0 maxfromiopmsgs = 64, maxtoiopmsgs = 210
Devices: Channel = 0, Target = 1, Lun = 0 [root@lala log]#
[root@lala log]# cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: ADAPTEC Model: RAID-1 Rev: 320P Type: Direct-Access ANSI SCSI revision: 02 [root@lala log]#
If I want to see each device separately I have to go to the controller's software by pressing ctrl-a at boot time.
