Hello,
Has somebody experience with Dell MD3600i and oVirt 3.2.1?
Host and oVirt are deployed on Fedora 18.
My infrastructure contains: 2 x powerconnect 6224 and this storage with two=
controllers
Both switch are in stack mode and storage is connect with four 10Gb ports i=
n same subnet (is better to use it without stack as two subnet?)
So, where is problem...I can create iSCSI storage domain, everything seems =
to be OK but when I want to add next host they cannot access this iSCSI tar=
get (in storage management tools is already added to host group)
And during this process I can see only on host console IO error, buffer err=
or and kernel BUG: soft lockup - CPU stuck etc...
Exists recommended way how involved iSCSI?
Thanks for any suggestions
Martin

For the first part I don't have an answer but the softlockups sound
familiar and the only solution I have found sofar that works reliable is
to switch back to kernel 3.6.10
I higher kernel level will sometimes work after a reboot but more often
it will cause softlockups as soon as multipathd is started.

Hello
I have (maybe similar?) problem with MD3620f (fibre channel array) and=20
rhev(h) 3.1.
problem is that MD36xxf is not listed in default multipath configuration.=
there was lots of errors in /var/log/messages

I had to manually add this to /etc/multipath.conf
device {
vendor "DELL"
product "MD36xxf"
product_blacklist "Universal Xport"
path_grouping_policy group_by_prio
getuid_callout "/lib/udev/scsi_id --whitelisted --device=3D/dev/%n"=
path_selector "round-robin 0"
path_checker rdac
features "2 pg_init_retries 50"
hardware_handler "1 rdac"
prio rdac
failback immediate
rr_weight uniform
no_path_retry 15
rr_min_io 1000
rr_min_io_rq 1
}
after multipathd restart errors are gone and multipath works correctly
It would be nice to have this in default multipath config (at least for=20
thin hypervisor)
btw. similar stuff on Dell's forum -=20

Hello,
Has somebody experience with Dell MD3600i and oVirt 3.2.1?
Host and oVirt are deployed on Fedora 18.
My infrastructure contains: 2 x powerconnect 6224 and this storage
with two controllers
Both switch are in stack mode and storage is connect with four 10Gb=
ports in same subnet (is better to use it without stack as two
subn=
et?)
So, where is problem...I can create iSCSI storage domain, everythin=
g
seems to be OK but when I want to add next host they cannot
access
this iSCSI target (in storage management tools is already added to
host group)
And during this process I can see only on host console IO error,
buffer error and kernel BUG: soft lockup =E2=80=93 CPU stuck etc...=
Could you please paste the log messages related to the errors above ?
Exists recommended way how involved iSCSI?
Thanks for any suggestions
Martin
