In VM 2.2, I had created multipath.conf entries for our Equallogic storage using whatever docs I could find and then the hit-and-miss method. Eventually got everything working, using a bonded active-backup connection.
In VM 3.1.1, I had to manually create the bond and then I was able to create the storage network within VM Manager OK. But the multipath.conf entry for Equallogic is more condensed than what I had created myself for version 2.2. So I was wondering if anyone had any experience with this or had any opinions as to which of the multipath.conf entries would be preferred over the other.
I read this thread:
2397578 It had some good information and also talked about editing the /etc/iscsi/iscsid.conf file, which I have not done.
So here's the multipath.conf entry I had created for VM2.2:
device {
vendor "EQLOGIC"
product "*"
path_grouping_policy multibus
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
features "1 queue_if_no_path"
path_checker readsector0
failback immediate
path_selector "round-robin 0"
rr_min_io 20
rr_weight properties
}
And here's what VM Manager created for VM3.1.1:
device {
vendor "EQLOGIC"
product "100E-00"
path_grouping_policy failover
failback immediate
no_path_retry 10
}
Both environments are working, but I'd like to have the VM3.1.1 environment working in the best possible way. I don't want to go back to the hit-and-miss method because that takes an awful lot of time and I don't have a lot of time to spare most days. So I would welcome any suggestions or opinions. Thanks!
