To make the loop 1 connections between the main rack and the expansion rack:
1. Unplug DP1-A on controller A from P1 (I/O-A) on disk enclosure 1 (S-1) and:
a. Connect DP1-A on controller A to P1 (I/O-A) on disk enclosure 27 (S-27).
b. Connect P1 (I/O-A) on disk enclosure 1 (S-1) to P2 (I/O-A) on disk enclosure 25 (S-25).
2. Complete the following verification steps:
a. Verify that the I/O modules on the added disk enclosure has been assigned an index number
of the next higher enclosure number.
b. In HP Command View EVA, verify that the newly added disk enclosure is listed under the
array hardware in the Navigation pane and the I/O module displays a good operational
status.
3. Unplug DP1-B on controller B from P1 (I/O-B) on disk enclosure 1 (S-1) and:
a. Connect DP1-B on controller B to P1 (I/O-B) on disk enclosure 27 (S-27).
b. Connect P1 (I/O-B) on disk enclosure 1 (S-1) to P2 (I/O-B) on disk enclosure 25 (S-25).
c. Repeat Step 2.
