Goal

This note describes what changes are needed on an Oracle Private Cloud Appliance Compute Node when attaching via fiber channel/switch to either an Oracle FS1 Flash Storage or to a Pillar Axiom Storage Array.

Solution

Modify /etc/multipath.conf by adding either or both of the following setting depending on if you have an Oracle FS1 Flash Storage or a Pillar Axiom Storage Array.

Note: If presenting LUN0 from FS1/Axiom you will be required to reboot the Compute Node for it to become visible.

for a FS1 add the following under "devices {"

device {

vendor "^Oracle( )?$"
product "^Oracle FS"
path_selector "round-robin 0"
path_grouping_policy group_by_prio
prio alua
path_checker tur
failback immediate

}

for an Axiom add the following under "devices {"

device {

vendor "^Pillar( )?$"
product "^Axiom"
path_selector "round-robin 0"
path_grouping_policy group_by_prio
prio alua
path_checker tur
failback immediate

}

Note: Please note that there are TWO spaces between the parenthesis "( )" for the vendor section.

vendor "^Oracle( )?$"

and

vendor "^Pillar( )?$"

After making the necessary changes you can either reboot the Compute Node or you can "service multipathd restart"

Example:

[root@ovcacn07r1 ~]# cat /etc/multipath.conf

## IMPORTANT for OVS do not blacklist all devices by default.
#blacklist {
# devnode "*"
#}

[....snip...]

device {
vendor "SUN"
product "ZFS Storage.*"
getuid_callout "/sbin/scsi_id -g -u -p 0x83 -s /block/%n"
prio alua
hardware_handler "1 alua"
path_grouping_policy group_by_prio
failback immediate
no_path_retry 10
rr_min_io 100
path_checker tur
rr_weight uniform
}

device {
vendor "^Oracle( )?$"
product "^Oracle FS"
path_selector "round-robin 0"
path_grouping_policy group_by_prio
prio alua
path_checker tur
failback immediate
}

device {
vendor "^Pillar( )?$"
product "^Axiom"
path_selector "round-robin 0"
path_grouping_policy group_by_prio
prio alua
path_checker tur
failback immediate
}

}
