Your customer installed the shelf firmware for their NS224 shelf over a week ago, and...

The question refers to a scenario where the shelf firmware for an NS224 shelf has not been upgraded on one of the NVMe shelf modules (NSM) after a week of installation.

The NSM is responsible for managing the communication between the drives and the I/O modules (IOM) in the shelf1.

The shelf firmware for the NSM is automatically updated when the NSM is inserted into the shelf or when the system is rebooted2.

If the automatic update does not work, the manual update process involves reseating the NSM, which means removing it from the shelf and inserting it back3.

Reseating the NSM triggers the firmware update and also resets the NSM’s state3.

The other options are not correct, because:

B. Reseating the disk in Bay 0 will not affect the NSM firmware update, as the disk is not connected to the NSM1.

C. Power cycling the shelf will disrupt the I/O operations and may cause data loss or corruption4.

D. Reseating the PSU of the shelf will not affect the NSM firmware update, as the PSU is not connected to the NSM1. References:
