Blacklisting by WWID Does Not Effect on OEL4 (Doc ID 780711.1)

Last updated on AUGUST 04, 2018

Applies to:

Linux Kernel - Version: 4.7 to 4.7
Linux x86-64

You have OEL4U7 installed. To blacklist the local SCSI device (e.g. /dev/sda) by wwid, you modify the /etc/multipath.conf as follows:

    blacklist {
    wwid        xxxx-xxxx-xxxx-xxxx
    }

where wwid for /dev/sda is found by:

#scsi_id -g -u -s /block/sda

Then you apply the new configuration by:

#multipath -F
#multipath -v2

However, /dev/sda is still initialized as a multipath device.

You have OEL4U7 installed and use native device-mapper-multipath-0.4.5 rpm package.
