Description
After replacement of a T3 controller disk is not detected by T3 even though green LED is on.

Steps to Follow
During a customer escalation, the decision was made to replace a T3 controller. FW version was 1.18.04.
After the maintenance action the following disk status was observed:

As you can see u1d9 appears to be missing even though it had not been removed and the green LED was on. Customer had even tried power cycling the T3 and u1d9 remained undetected.
Suggested workaround that enabled T3 to re-detect disk:
- pull u1d9 from the array
- while it is out record the vendor and model number of the drive and any other  info on it
- tail the t3 syslog to see if it recognizes the drive as missing
- after it is out for 5 full minutes, re-insert it and observe the LED's
- if it is recognized correctly you should see LED's flashing between u1d9 and probably u1d1 as the sysarea is being copied
- look at fru list and fru stat again, look at vol list and vol stat
After this workaround was implemented the following fru list was seen:
