Check Current State of Compute Node SSDs

Use xtcheckssd periodically to make sure the SMW database has the current state of compute node SSDs.

This procedure is intended only for XC systems that have compute nodes with SSDs, such as DataWarp SSDs or Intel® Xeon Phi™ "Knights Landing" processors.

Use this command after an initial installation, SSD hardware change, or system update. Cray also recommends running xtcheckssd periodically (daily/weekly).

Run xtcheckssd to ensure that SMW databases have the current state of compute node SSDs.
