Creating Additional Host Ids (Optional) - Sun Microsystems StorEdge 3000 Series Installation, Operation And Service Manual

Caution – The channels of redundant controllers must be the same. For example, if
the primary controller uses channel 2 to connect to a group of drives, the secondary
controller must also use channel 2 to connect to the same group of drives. Changes
to the primary controller are automatically made to the secondary controller.

Creating Additional Host IDs (Optional)

All RAID arrays are preconfigured when they arrive from the factory.
Default host channel IDs are:
Channel 1 ID 0 (primary controller)
I
Channel 3 ID 1 (secondary controller)
I
Each host channel might have two editable ID numbers:
Primary controller ID
I
Secondary controller ID
I
Each ID number must be a unique number within the host channel. You can:
Edit each host ID number to change the SCSI target number of each controller
I
host channel that is seen by the host.
Add additional host ID numbers (by adding a second host ID to channels 1 and 3,
I
and additional host IDs if you make Channel 2 into a host channel).
Note – To map 128 partitions into 128 LUNs, you must add additional host IDs. A
minimum of four host IDs are required; a maximum of six host IDs are possible. For
details on mapping 128 LUNs, refer to
page
To select a unique ID number for a host channel:
1. Choose "view and edit Scsi channels."
2. Select the host channel on which you want to edit the Primary/Secondary ID.
3. Choose "view and edit scsi Id."
If a host ID has already been assigned to that channel, it is displayed.
4. Select the existing host ID and press Return.
5. Choose "Add Channel SCSI ID."
