[PVE-User] Need help with iscsi Dell MD3200i and MULTIPATH

Wed Dec 11 19:55:09 CET 2019

Hi there

I am using PVE 6.1-3 and trying to use iscsi over Dell Storage MD3200i.
I have successful deploy the storage to give access to block device via 2
different IPs
How ever, I can not deploy multipath properly.
When I try multipath -ll give me nothing or multipath -v3 tells me that the
wwid is not in the file
BTW, I have used this site as reference:
https://pve.proxmox.com/wiki/ISCSI_Multipath
<https://pve.proxmox.com/wiki/ISCSI_Multipath#Dell>

https://icicimov.github.io/blog/virtualization/Adding-iSCSI-shared-volume-to-Proxmox-to-support-Live-Migration/

Here's the /etc/multipath.conf:
defaults {
        polling_interval 3
        path_selector "round-robin 0"
        max_fds "max"
        path_grouping_policy multibus
        uid_attribute "ID_SERIAL"
        rr_min_io 100
        failback immediate
        no_path_retry queue
        }

blacklist {
        wwid .*
devnode "^sda"
device {
                vendor "DELL"
                product "Universal Xport"
        }
}
devices {
device {
                vendor "DELL"
                product "MD32xxi"
                path_grouping_policy group_by_prio
                prio rdac
                #polling_interval 5
                path_checker rdac
                path_selector "round-robin 0"
                hardware_handler "1 rdac"
                failback immediate
                features "2 pg_init_retries 50"
                no_path_retry 30
                rr_min_io 100
                #prio_callout "/sbin/mpath_prio_rdac /dev/%n"
        }
}
blacklist_exceptions {
        wwid "361418770003f0d2800000a6c5df0a959"
}
multipaths {
        multipath {
                wwid "361418770003f0d2800000a6c5df0a959"
                alias mpath0
        }
