Re: Adaptec RAID SCSI 2100S

[Juan Pablo Abuyeres]

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.
