I am currently running XS 6.0.2 w/ HF XS602E001 & XS602E002 applied running on Cisco UCS B200-M3 blades. XS seems to be functioning ok, except that i cannot see the subnet assigned to my SAN, and as a result, i cannot add any SR for VM storage.
If i missed anything or more info is needed, please let me know.
After booting the OS via iSCSI, do you notice any NICs from Xen ?
lspci | egrep -i 'net|eth'
The iSCSI vNIC that we create in adapter is only used for booting OS via iSCSI. Once the OS is loaded and if we need to access storage LUNs via iSCSI, we need additional regular vNICs defined in Service profile / VIC.
If you have a NIC,then as a first step, you can verify the IP connectivity to iSCSI storage server.
If you have the NIC and configured an IP address, please make sure it is configured with necessary VLANs in the vNIC ( service profile )
Since we have iSCSI storage connected to FI via Appliance port, make sure you have created the VLANs under Appliance cloud too.
I have 2 NICs that show up in XenCenter. Nic A is the vNIC associated with VLAN1 and provide the uplink to the rest of the network. The second NIC in XenCenter matches the MAC of the vNIC used to boot XenServer, so the NIC used for booting the OS is visible in XenCenter.
I have tried many different thing on my own to resolve this issue. I believe i have already tried adding a 3rd vNIC to the service profile for VM iSCSI traffic, but with make another attempt.
When configuring the vNIC for VM iSCSI traffic, do I only need to add the 3rd vNIC, or do i need to create both a vNIC and second iSCSI vNIC with Overlay vNic pointing to newly created (3rd) vNIC? My understanding is that the iSCSI vNICs are only used for booting, but I am not 100% sure.
Thanks again for the help!
Thanks for the screen shots.
Let us assume that you have configured vNIC 1 ( eth0 in Xen ) with an IP address that belongs to iSCSI VLAN and is used as iSCSI initiator.
iSCSI target ( SAN array ) is directly connected to FI via Appliance port.
What exactly happens when you try to ping ( eth0 IP address as source ) iSCSI target IP address ?
