After a LUN recovered from a failure, we ran the fdisk -l command on the Linux host, but could not see the recovered LUN in the output.Application server operating system: SUSE Linux Enterprise Server 11 (x86_64)
A LUN failure during I/O operations causes large amounts of I/O errors on the LUN. As a result, the LUN became abnormal.
When we ran the fdisk -l command to list all devices, the fdisk -l command sent an I/O to read the LUN-related information. Since the LUN was already abnormal, the fdisk -l command could not be sent to the LUN. As a result, the LUN was not displayed in the output even if it was recovered from the failure.
