Prioritizer '' not found in /lib64/multipath

Trying to finalise multipath.conf on a SLES11SP2 server for connection to an EVA SAN and I’m getting this:

# multipath -v2 -d Nov 19 12:11:37 | Prioritizer '' not found in /lib64/multipath Nov 19 12:11:37 | Prioritizer '' not found in /lib64/multipath

We have other SLES11SP2 boxes, however they are connected to a NetApp SAN. The proposed multipath.conf is:

defaults { user_friendly_names no } blacklist { devnode "^hd[a-z][0-9]*" devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^cciss!c[0-9]d[0-9].*" devnode "sd[a]$" } devices { device { vendor "HP" product "HSV2[01]0|HSV300|HSV4[05]0" getuid_callout "/lib/udev/scsi_id -g -u /dev/%n" hardware_handler "0" path_selector "round-robin 0" path_grouping_policy group_by_prio failback immediate rr_weight uniform rr_min_io 100 path_checker tur prio "alua" #no_path_retry fail no_path_retry 18 } }

The /lib64/multipath directory contains:

drwxr-xr-x 2 root root 4096 Nov 13 20:37 ./ drwxr-xr-x 9 root root 12288 Nov 13 20:43 ../ -rwxr-xr-x 1 root root 10360 Nov 27 2012 libcheckcciss_tur.so* -rwxr-xr-x 1 root root 10416 Nov 27 2012 libcheckdirectio.so* -rwxr-xr-x 1 root root 10384 Nov 27 2012 libcheckemc_clariion.so* -rwxr-xr-x 1 root root 10328 Nov 27 2012 libcheckhp_sw.so* -rwxr-xr-x 1 root root 10336 Nov 27 2012 libcheckrdac.so* -rwxr-xr-x 1 root root 6248 Nov 27 2012 libcheckreadsector0.so* -rwxr-xr-x 1 root root 14680 Nov 27 2012 libchecktur.so* -rwxr-xr-x 1 root root 10440 Nov 27 2012 libprioalua.so* -rwxr-xr-x 1 root root 6112 Nov 27 2012 libprioconst.so* -rwxr-xr-x 1 root root 10336 Nov 27 2012 libpriodatacore.so* -rwxr-xr-x 1 root root 6208 Nov 27 2012 libprioemc.so* -rwxr-xr-x 1 root root 10312 Nov 27 2012 libpriohds.so* -rwxr-xr-x 1 root root 6216 Nov 27 2012 libpriohp_sw.so* -rwxr-xr-x 1 root root 10320 Nov 27 2012 libprioontap.so* -rwxr-xr-x 1 root root 6208 Nov 27 2012 libpriorandom.so* -rwxr-xr-x 1 root root 6216 Nov 27 2012 libpriordac.so* -rwxr-xr-x 1 root root 10392 Nov 27 2012 libprioweightedpath.so*

Any assistance appreciated.

Hi
Have you had look here or searched the knowledge base?
https://www.suse.com/documentation/sled11/stor_admin/data/bpjpirk.html

Since SP2 is out of support (unless you have LTSS), how up to date is the system?

The server has multipath-tools-0.4.9-0.68.1 installed. I checked the knowledge base, however it’s not particularly specific:

Our multipath.conf file conforms with that structure - the prio setting is in the devices section.

I think the message may be spurious/cosmetic, as it probably relates to the devices listed as sdr and sds which are iDRAC virtual devices. All the OES11 servers we have built until now have been on HP BL460c blades with NetApp storage, or VMs (See near the bottom).

Hi
So these systems are all OES 11?
