You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Hi,

After create the LUN and attach on the host You can run "echo 1 > /sys/block/device_name/device/rescan" to scan the disk or reboot your system.
After run "fdisk -l " to list all disks, you will see internal disks and luns.

Hey ! Thanks for your update.

And when i googled i saw something like below to add the lun to linux host.

Code:
echo > 1 "proc/scsi/sci"

Or

Code:
echo "- - -" > /sys/class/scsi_host/host<ID>/scan

Use the below commands to identify the newly added lun in the server.

dmesg|grep scsi
echo "- - -" > /sys/class/scsi_host/host5/scan

Hi,

Red Hat documentain has the command "echo 1 > /sys/block/device_name/device/rescan", if not worked reboot your system.
