Blacklisting Non-Multipathed Devices in /etc/multipath.conf
The
/etc/multipath.conf
devices should be listed. For example, local IDE hard drives and floppy drives are not normally
multipathed. If you have single-path devices that multipath is trying to manage and you want
multipath
NOTE: In SLES 10 SP3, the keyword devnode_blacklist has been deprecated and replaced with the
keyword blacklist.
For example, to blacklist local devices and all arrays from the
multipath, the
blacklist {
wwid 26353900f02796769
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st|sda)[0-9]*"
devnode "^hd[a-z][0-9]*"
devnode "^cciss!c[0-9]d[0-9].*"
}
You can also blacklist only the partitions from a driver instead of the entire array. For example, using
the following regular expression would blacklist only partitions from the cciss driver and not the
entire array:
^cciss!c[0-9]d[0-9]*[p[0-9]*]
After you modify the
on your system, then reboot in order for the changes to take effect.
Afterwards, the local devices should no longer be listed in the multipath maps when you issue the
