after upgrading to 4.20.39-1.el7 sas multipath stopped being detected I did a diff to the two files Is the current behaviour the correct one or the previous one ? I think sas multipath should also be detected no ? [root@g1-car0136 etc]# diff multipath.conf multipath.conf.201809031555 1c1 < # VDSM REVISION 1.6 ---
# VDSM REVISION 1.5 101,109d100 < } < < # Whitelist FCP and iSCSI devices. < blacklist { < protocol ".*" < } < < blacklist_exceptions { < protocol "(scsi:fcp|scsi:iscsi)"

It should be detect it this is shared storage that you want to use in oVirt It should not be detect if you have local disk using sas. So we really cannot know. [root@g1-car0136 etc]# diff multipath.conf multipath.conf.201809031555

oVirt does not officially support sas, but this should work: protocol "(scsi:fcp|scsi:iscsi|scsi:sas)" The best way to configure it is to add a dropin configuration file: $ cat /etc/multipath/conf.d/my.conf blacklist_exceptions { protocol "(scsi:fcp|scsi:iscsi|scsi:sas)" } See also this thread: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/RFEQ5JK2RZM3Q7U... I suggest you file a bug for this here: https://bugzilla.redhat.com/enter_bug.cgi?product=vdsm Nir

oVirt does not officially support sas, but this should work:
protocol "(scsi:fcp|scsi:iscsi|scsi:sas)"
The best way to configure it is to add a dropin configuration file:
$ cat /etc/multipath/conf.d/my.conf
blacklist_exceptions { protocol "(scsi:fcp|scsi:iscsi|scsi:sas)" }
Actually, to enable sas support, you can do this: # cat /etc/multipath/conf.d/enable-sas.conf blacklist_exceptions { protocol "scsi:sas" }

Thank you very much for your answer, somehow the exception did not work, but I guess it is ok it is not a shared storage, it is a dual sas port external JBOD box. I guess multipath is not really needed in that case
In almost the same configuration, the protocol was detected as being scsi:unspec, did you try that ?
