Upgrading solid-state drive (SSD) firmware using the CLI

You can upgrade a solid-state drive (SSD) by downloading and applying firmware updates using the SAN Volume Controller command-line interface (CLI).

This procedure upgrades firmware on a solid-state drive (SSD) that is internal to a supported SAN Volume Controller node. If the upgrade could cause any VDisks to go offline, the -force option is required. For example, a firmware update to a managed MDisk requires the -force option.

Perform the following steps to upgrade SSD firmware:

Run the lsnodedependentvdisks command for the node that you are upgrading. If any VDisks are returned, continuing with this procedure will take the VDisks offline. To avoid losing access to data, you must mirror the VDisks before continuing with this upgrade procedure.
Locate the firmware upgrade file at the IBM® Support for SAN Volume Controller (2145) Web site: Support for SAN Volume Controller (2145) Web site
Download the firmware upgrade file to the /home/admin/upgrade directory.
Run the applymdisksoftware command as follows. You must specify the firmware file name and the MDisk name or ID of the SSD:
```
svctask applymdisksoftware -file filename mdisk name | id
```
To apply the upgrade even if it will cause one or more VDisks to go offline, specify the -force option.
Attention: Only use the -type fpga option, which upgrades Field Programmable Gate Array (FPGA) firmware, under the direction of an IBM service representative.
