Hello

I have a Host with LocalOnHost storage only.

Trying to blacklist the local disks from multipath:

PV         VG     Fmt  Attr PSize PFree
/dev/sda1  HostVG lvm2 a--  8.18t     0
/dev/sdb4  HostVG lvm2 a--  1.64t 24.00m

As you can see we need to blacklist these devices:

36b8ca3a0ea18e4001a95ba4832bcb7ea
36b8ca3a0ea18e4001a95b9f82df5609b

scsi-36b8ca3a0ea18e4001a95b9f82df5609b -> ../../sda
scsi-36b8ca3a0ea18e4001a95b9f82df5609b-part1 -> ../../sda1
scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea -> ../../sdb
scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part1 -> ../../sdb1
scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part2 -> ../../sdb2
scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part3 -> ../../sdb3
scsi-36b8ca3a0ea18e4001a95ba4832bcb7ea-part4 -> ../../sdb4

After making blacklist changes, you can see in "syslog_errors,"
multipathd does not like my blacklist syntax.

Do you see errors in the multipath.conf file?

Thanks
Doug
