Storage I/O Blocking

Hi, I suggest you power off the server, remove the hard disk, and then insert it.
Check whether the hard disk is normal.
To remove a hard disk, hold the ejector lever of the hard disk tray, pull out the hard disk about 3 cm, and wait for the disk to stop working. Then wait at least 30 seconds until the hard disk stops rotating and remove the hard disk from the server. If a disk is removed and inserted within 30 seconds, there are risks that the disk cannot be identified.
