DM Multipath

[Steven McCoy · Accepted solution]

What does this say?:

ls /dev/disk/by-id/

Also, would you mind posting your /etc/multipath.conf file, please?

Can you flush the device?

multipath -F

How about deleting the sd device associated with mpath4?

echo "1" > /sys/block//device/delete

It should be deleted now.

ls -l /dev/sd*

Rescan for drives.

echo "1" > /sys/class/fc_host/host0/issue_lip
echo "1" > /sys/class/fc_host/host1/issue_lip

See if they show up.

ls -l /dev/sd*

Re-run the multipath commands.

multipath -v2
multipath -ll
