Troubleshooting Steps

NOTE: This is a sub-set of <Document: 1018272.1> Troubleshooting Sun StorEdge[TM] T3 Configuration.

This document will help with faulted loop cards based on similar "fru stat"output below:

LOOP    STATUS   STATE       MODE        CABLE1    LB  CABLE2    LB  TEMP
------  -------  ----------  -------     --------- --  --------- --  ----
u1l1    ready    enabled     master      -         -   installed 10  27
u1l2    ready     <strong>disabled</strong>     slave       -         -   installed 11  33
u2l1    ready    enabled     master      installed 10  -         -   27
u2l2    offline

1. Enable loop card with "enable u#[1|2]" command.

storage-t3b:/:<3>enable u1|2

2. Verify that the loop card is now ready and enabled with the "fru stat" command.

NOTE: Wait about 1 minute before running "fru stat" as to allow the array to recover.

3. If the loop card is still not ready-enabled, then replace loop card.
