Enclosure Considerations - Adaptec DuraStor 7220SS User Manual

Enclosure Considerations

The DuraStor Storage Subsystem includes SEPs. The controller
provides information to the user via the enclosure LEDs and the
host interface.
The controller uses a standard set of SCSI commands to
communicate with the SEPs via back-end disk channels. This
communications path is managed by the controller and is
transparent to the user. However, when the user sets up the
storage system, SCSI ID conflicts must be avoided and the
controller's SCSI ID must be set within the range that the SEP can
respond to. (Some SEPs are narrow devices and can only see
certain ranges of SCSI IDs, such as 0-7 or 8-15.)
To set the controller's SCSI ID on each disk channel:
1
From the System Menu, select Configuration Menu.
2
Select Channel Configuration, and select the channel you wish
to set up.
The system prompts you through several items, including the
Initiator SCSI ID.
3
Select the appropriate SCSI ID.
Note: You may want to do all the channels at one time
before rebooting the controller.
4
Reboot the controller.
If you are using an enclosure that does not contain an SEP, the
DuraStor 6200S RAID controller's internal SAF-TE firmware is not
activated. In this situation, the internal RAID code operates as
usual, but the controller cannot signal individual disk slot status
and array health status to the user via the enclosure LEDs.
