Subject: [PATCH RESEND] mpi3mr:Fix duplicate device entries when scan through sysfs
Date: Thu, 14 Oct 2021 11:24:25 +0530 [thread overview]
Message-ID: <20211014055425.30719-1-sreekanth.reddy@broadcom.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 915 bytes --]
When the user scans the devices through 'scan' sysfs using below
command then the user will observe duplicate device entries
in lsscsi command output.
echo "- - -" > /sys/class/scsi_host/host0/scan
Fix is to set the shost's max_channel to zero.
