RETAIN tip: H207645
The IBM Flex System Chassis Management Module (CMM) event log can report errors for the IBM Flex System V7000 Storage Node, type 4939, power mid-plane (PIB).
The CMM reports errors similar to the following messages:
| ||voltage (PIB 12V) is not redundant and operational with minimal resources. |
voltage (PIB 5V) redundancy degraded.
This reporting issue can occur when either a controller canister or expansion canister is inserted into an IBM Flex System V7000 Storage Node. This issue also can occur when an IBM Flex System V7000 Storage Node is inserted into an IBM Flex System Chassis.
The system can be any of the following IBM servers:
- Flex System V7000 Storage Node, type 4939, any model
This tip is not software specific.
This tip is not option specific.
The following system firmware level is affected:
This behavior will be corrected in a future release of IBM Flex System V7000 code.
The target date for this release is second quarter 2013.
The file will be available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and Operating system on IBM Support's Fix Central web page, at the following URL:
These reporting errors can typically be cleared by performing one of the following two actions:
From the CMM Chassis view web interface:
- Right-click on one of canisters associated with the affected IBM Flex System V7000 Storage Node.
- Select Restart System Mgmt Processor.
From the CMM Service and Support Advanced view web interface:
- Select the Service Reset tab.
- Select one of the canisters of the affected IBM Flex System V7000 Storage Node.
Note: The Virtual Re-seat will power off the selected canister. I/O will fail over to the alternate canister until the original canister is back up and running.
- From the Reset menu, select Virtual Re-seat.
- If the PIB error has not been cleared, repeat Steps 1 through 3 for the alternate canister, but only after the original canister is back up and operational.
If neither of these software actions clear the event log error message, physically re-seat the IBM Flex System V7000 Storage Node enclosure.
This action should be performed during a scheduled maintenance cycle, because this actions will require users to power down the IBM Flex System V7000 Storage Node.
If none of these actions clear the PIB event, contact IBM Service and Support.
This issue has been found when either a controller canister is inserted into the IBM Flex System V7000 Storage Node, or the IBM Flex System V7000 Storage Node is inserted into the IBM Flex System Chassis. The system is reporting a transient power condition that is not cleared when the power stabilizes.
Resetting the System Mgmt Processor, either by way of software or by physically re-seating the hardware, forces the system to re-read the power lines on the PIB and clears the previous event.
