problem with ISCSI Traffic dropping
Got a bit of an ongoing issue with or 2 hyper-v (scvmm) hosts connected to our dell md3200i san
i'm getting thousands of error ID: 9, 39, 139 on both hyper-v servers, plus the SAN itself is kicking out disconnection errors
everything seems to be functioning okay, but services (cluster drives) drop out briefly, usually out of hours thankfully..
both of our servers have 8 1gb/lan ports and the san has two controllers, so 2 x 4ports
the configuration for each server is:
3ports aggregated to 3gbps on our main network subnet 172.16.*.*
1port connected to our other hyper-v server on the subnet 172.15.*.*
4 ports seperately connected to our SAN switch with different subnets for each port so..
this should give us failover capacity if one controller goes down, or if a NIC fails.
by the way, both Servers run server 2008R2 SP1 with failover clustering and the latest version of SCVMM.
the san is reporting everything as ok, all adapters are IP4 with jumbo frames (9000) enabled.
server adapters are a mix of broadcom and Intel...and they are Dell R610's if that helps.
oh and the san switch is a D-link 24port gigabit managed switch (with jumbo enabled) and separate from the main network.
if anyone has any suggestions I would be very appreciative, If you need any information please let me know.
I just realised, this might be more suited to the virtualisation section, although...it is hardware.
