The storage subsystem currently contains a drive enclosure in which one or both of the ESM canisters are uncertified.
The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.

|
If the uncertified status resulted because... |
Then... |
Only one of two certified ESM canisters was replaced with an uncertified ESM canister |
Go to step 2. |
The only certified ESM canister or both certified ESM canisters were replaced with uncertified ESM canister(s) |
Go to step 3. |
An entire uncertified drive enclosure (all ESM canisters are uncertified) replaced a certified drive enclosure |
The uncertified drive enclosure must be removed and replaced with a certified drive enclosure.
Go to step 3.
|
An entire uncertified drive enclosure (all ESM canisters are uncertified) was inserted in addition to the certified drive enclosures |
Remove the uncertified drive enclosure. For future storage expansion, only certified drive enclosures can be added to existing storage subsystems. In addition, only certified drive enclosures can replace certified drive enclosures.
When finished, go to step 6.

Perform the following steps to identify the uncertified ESM canister:
Caution: Risk of Data Loss. Make sure you correctly identify the uncertified ESM canister. Removing the remaining certified ESM canister while I/O is in progress can cause data loss.
a |
Select the affected enclosure's Drive Enclosure Components button in the Physical View of the Subsystem Management Window. |
b |
Select the ESM canister icon in the left-hand pane of the Drive Enclosure Component Information dialog. |
c |
From the right-hand pane of the Drive Enclosure Component Information dialog, find the ESM canister listing the following information:
ESM card status: Uncertified.
|
d |
For the uncertified ESM canister, note the information given for Location.
You will need this information for step f.
|
e |
Select Locate Enclosure.
The indicator lights on the drive enclosure containing the uncertified ESM canister will be blinking.
|
f |
From the back of the drive enclosure, locate the uncertified ESM canister using the Location information you noted in step d.
When finished, go to step 3.
|
|
3 |
If... |
Then... |
The cables are connected directly to the ESM canister |
Label each cable to ensure that they are properly reconnected when the ESM canister is replaced.
Remove the cables.
Go to step 4.
|
The cables are connected to an interface transceiver such as a SFP |
Label each interface transceiver to ensure that they are properly reconnected when the ESM canister is replaced.
Leave the cables connected and remove the interface transceivers from the ESM canister.
Go to step 4.
|
|
4 |
Replace all uncertified components with certified components. |
5 |
Using the labels created in step 3, reconnect the cables or transceivers to the replaced canister(s). Wait 40 seconds, then go to step 6. |
6 |
If applicable, fix any loss of redundancy problems reported by Recovery Guru before continuing to step 7. |
7 |
Click the Recheck button to rerun the Recovery Guru to ensure the failure has been fixed.
If... |
Then... |
No failures are reported |
You are finished with this procedure. |
An uncertified ESM canister is still reported |
- You replaced an uncertified ESM canister with another uncertified ESM canister. After obtaining a certified ESM canister, repeat steps 1 through 7 to replace the uncertified ESM canister with the certified ESM canister. If you are unsure if an ESM canister is certified, contact your technical support representative.
- If you are certain that the new ESM canister is certified, stop all I/O to the storage subsystem, turn the power switches off and on again on the back of the controller enclosure, and repeat step 7.
- If you are unable to correct the uncertified status after performing steps 1 through 7, contact your technical support representative.
