Use the Confirm Firmware Upgrade panel in the SAN Volume Controller Console to
verify the upgrade of the solid-state drive (SSD) firmware that runs on a standard processor on the drive.
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 . 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.
