Re: multipathd can't remove paths
Multipathd might be relying on the kernel's hotplug information, which is kept until the system is rebooted or the sysadmin explicitly removes it. This is required to handle smoothly a situation where a disk vanishes temporarily, then comes back.
Are the disk devices still visible if you run "ls /sys/block"? If so, use /sys/block/
Example:
To tell the kernel that /dev/sdaa is gone for good:
multipath -F
echo 1 >/sys/block/sdaa/device/delete
MK

multipathd> list maps
mpath4 dm-8 [no scheduled failback]
[root@wshq-eod03 hbanyware]# echo 1 > /sys/block/dm-8/device/delete
-bash: /sys/block/dm-8/device/delete: No such file or directory
The result from multipath -ll is the same after running multipath -v3 also.
