What you call SAS is any block device we might want to attach directly and let oVirt manage. I was doing the same thing on old HPE hardware, using old smart array controlers. I gave the raw device to ovirt. After an upgrade, it fails as it was
blacklisted. I need to add it to the blacklist exceptions:
cat /etc/multipath/conf.d/enable-sas.conf
blacklist_exceptions {
protocol "cciss"
}
I think your default rule is quite hard, and can brake many existing setup:
multipathd show blacklist
...
protocol rules:
- blacklist:
(config file rule) .*
- exceptions:
(config file rule) (scsi:fcp|scsi:iscsi)
(config file rule) cciss <-- mine
