Action
|
|---|
|
1
|

|
6
|
If you are converting to a...
|
Then...
|
|
System with nonmirrored disks
|
- Disconnect all cabling from the
Channel B loop on the local
node.
- Repeat for the partner node.
|
|
System with mirrored disks or a redundant Channel B loop
|
- Connect the local node to the
open Channel B loop in its local
disk shelves, as described in the
appropriate disk shelf guide.
- Repeat for the partner node.
|
