Confirm FPGA upgrade: Panel help

Use the Confirm FPGA Upgrade panel in the SAN Volume Controller Console to verify the upgrade of the Field Programmable Gate Array (FPGA), which is a programmable logic chip that is stored onsolid-state drives (SSDs) on the node. You should not upgrade FPGA chip unless directed to do so by an IBM® service representative. During the FPGA upgrade, the SSD and the managed disk (MDisk) go offline and are not available to the cluster. The upgrade process takes approximately 30 minutes to complete.

Attributes

The following attributes are displayed:

MDisk Name

Displays the name of the managed disk (MDisk) that is associated with the SSD on the node.

For firmware updates to SSDs, each SAN Volume Controller 2145-CF8 node can contain up to four solid-state drives (SSDs) which are presented to SAN Volume Controller Console as managed disks (MDisks). Each of these MDisks contains two programmable components that are stored on the drive itself which can be upgraded. The upgradeable components include the drive firmware and the Field Programmable Gate Array (FPGA), which is a programmable logic chip that is stored on the SSDs in the node. If you want to upgrade the SSD firmware, you can download the upgrade files from the following Web site: Support for SAN Volume Controller (2145) Web site.

State

Displays the state of the MDisk. The following values are possible:

Online

Indicates that the MDisk is online and available. All paths to the MDisk are available.

Degraded Paths

Indicates that the MDisk is not accessible to one or more nodes in the cluster. Degraded path state is most likely the result of incorrect configuration of either the disk controller or the fibre-channel fabric. However, hardware failures in the disk controller, fibre-channel fabric, or node could also be a contributing factor to this state. Complete the following actions to recover from this state:

Verify that the fabric configuration rules for storage systems are correct.
Ensure that you have configured the storage system properly.
Correct any errors in the error log.

Degraded Ports

Indicates that one or more 1220 errors have been logged against the selected MDisk. The 1220 error indicates that the remote fibre-channel port has been excluded from the MDisk. This error may cause reduced performance on the storage controller and usually indicates a hardware problem with the storage controller. To fix this problem you must resolve any hardware problems on the storage controller and fix the 1220 errors in the error log. To resolve these errors in the log, select Service and Maintenance > Run Maintenance Procedures. On the Maintenance Procedures panel, select Start Analysis. This action displays a list of unfixed errors that are currently in the error log. For these unfixed errors, select the error name to begin a guided maintenance procedure to resolve these errors. Errors are listed in descending order with the highest priority error listed first. Highest priority errors should be resolved first.

Excluded

Indicates that the MDisk has been excluded from use by the cluster after repeated access errors. Run the directed maintenance procedures to determine the problem. You can reset an MDisk and include it in the cluster by running the include task.

Offline

Indicates that the MDisk is offline and unavailable. All paths to this MDisk have been lost.

Mode

Displays the current mode of the MDisk that is associated with the SSD on the node. The following values are possible:

Unmanaged: Indicates that the MDisk that is associated with the SSD on the node is currently not used by the cluster. You can only upgrade FPGA level on unmanaged MDisks.
Managed: Indicates that the MDisk is assigned to an MDisk group and is providing extents that VDisks can use.
Image: Indicates that the MDisk is assigned directly to a VDisk with a one-to-one mapping of extents between the MDisk and the VDisk.

MDisk Group Name

Displays the name of the MDisk group that the SSD belongs to.

SSD Slot

Displays the slot identifier where the SSD is located on the node.

Node

Displays the name of the node that the SSD is located.

Firmware Level

Displays the current level of the firmware for the SSD.

FPGA Level

Displays the current level for the FPGA chip.

Actions

The following actions are available:

Confirm: Click this button to confirm that the selected MDisks is the SSD to be upgraded.
Cancel: Click this button to exit this panel without upgrading the SSD firmware.
