Changes

Cause

The disk drives had been spun down in case there's no IO on them. HMP send
some SCSI commands for disk inventory report, which will trigger some errors,
and spun up the disk drives.

please check below item if no error reported.

- Operating system is not reporting any disk errors.
- RAID HBA shows all physical disks healthy. Zero error counters and SMART data OK.
- RAID HBA shows all the Logical Volumes in Optimal health.

If no warning or error level event logged and just the messages are 'notice' level only.　We can safe ignore these messages.

Solution

Upgrade HMP to 2.3.0 or higher releases. If messages still output during system booting, open a Hardware Service Request to Support.
Similar Bug 16800787 fixed by HMP 2.3 and higher release.
