Subject: [PATCH] scsi: Retry I/O for Notify (Enable Spinup) Required error.
Date: Tue, 29 Jun 2021 08:58:26 -0700	[thread overview]
Message-ID: <20210629155826.48441-1-quat.le@oracle.com> (raw)

If the device is power-cycled, it takes time for the initiator to
transmit the periodic NOTIFY (ENABLE SPINUP) SAS primitive, and for the
device to respond to the primitive to become ACTIVE. Retry the I/O
request to allow the device time to become ACTIVE.
