Hot plug capable
NVMe Flash adapter maximum write capability
Determine whether the NVMe Flash adapter maximum write capability is depleted by completing the
following steps:
1. Type the following command at the Linux command line and press Enter: nvme smart-log
/dev/nvmeX, where nvmeX is the resource name of the NVMe Flash adapter.
2. If the critical_warning field is 1 (bit 0 is set) and the percentage_used field is 90% or greater, replace
the NVMe Flash adapter.
Note: The replacement of depleted NVMe Flash adapters is covered during the system warranty period.
After the warranty period has expired, the cost that is incurred for the replacement of depleted NVMe
Flash adapters is not covered under maintenance contracts, and is the responsibility of the customer.
