MSA 2012i Multipath
OS: Win2003 R2 SP2
iSCSI Host (Initiator) = Microsoft iSCSI Initiator v2.07
NIC1 = NC360T
NIC2 = NC373i
Versions on MSA:------------------------
Controller A Versions
---------------------
Storage Controller CPU Type : Celeron 566MHz
Storage Controller Firmware : J210R10
Storage Controller Memory : F300R21
Storage Controller Loader : 15.010
Management Controller Firmware: W421R07
Management Controller Loader : 12.013
Expander Controller Firmware : 2042
CPLD Revision : 27
Hardware Revision : LCA 55
Host Interface Module : 50
Host Interface Module Model : 2
Controller B Versions
---------------------
Storage Controller CPU Type : Celeron 566MHz
Storage Controller Firmware : J210R10
Storage Controller Memory : F300R21
Storage Controller Loader : 15.010
Management Controller Firmware: W421R07
Management Controller Loader : 12.013
Expander Controller Firmware : 2042
CPLD Revision : 27
Hardware Revision : LCA 55
Host Interface Module : 50
Host Interface Module Model : 2
------------------------------
Configuration: Controller A port 1 and Controller B port 1 plug into Switch A (HP 2824). (CA2 and CB2 plug into SWB which is also an HP 2824). Each switch is then connected to one of the NICs in the server. (Like the diagram in the HP StorageWorks 2012i User guide, Page 42)
The Problem:
When I try to configure the Initiator for Multipath it gives me an error about "Too Many Connections".
Another problem: If I pull out Controller A, Controller B won't take control of the vDisk(s) currently assigned to Controller A, even though "show redundancy-mode" returns this:
System Redundancy
-----------------
Redundancy Mode : Active-Active
Redundancy Status : Redundant Operation
Controller A Status : Operational
Controller A Serial Number: xxxxxxxxxxxx
Controller B Status : Operational
Controller B Serial Number: xxxxxxxxxxxx
Any ideas? Need more info? let me know.
Thanks,
Scott

Re: MSA 2012i Multipath
did you get any solution for your problem now ? We have the same problem. Ther is an DL380G5 with an 2-Port ISCSI Card. These 2 Ports are configured with 2 IP Adresses in different Subnets. Then we have a MSA2000 with 2 MSA2012i Controllers configured Port 0 of each Controller with a Ip Adress in the Range of the ISCSI Card on the DL380 Server.
If i start now the Microsoft ISCSI Initiatior, i only can connect to the Controller A in the MSA2000. The Second Controller B shows a Connect but if you click on details there is no Volume connected. So i can click the multipath Option in the Initiator but i have no failover. These Causes an Copy abort if i draw the connect to controller A. If I replace the connect the copy goes on. But Controller B has no function.
If there is any Tip, Hint or anything like that please let me know.
Thanks
Stephan

Re: MSA 2012i Multipath
Do you have the J210R10 firmware available? I'm having problems with the new firmware J210P03 and can not find it anywhere. I would appreciate it if you could send it to me.

Re: MSA 2012i Multipath
I have yet to get the iSCSI Initiator to do multipathing. More experimentation, no doubt will find what we are doing wrong.

Re: MSA 2012i Multipath
Scott - was just curious how you made out on this? We're in the same boat with the MSA 2012i except we have two Cisco 3750 network switches (instead of the HP switches) and an additional Windows 2003 32-bit box we want to cluster with the first one using MCS.
Any experiences/docs would be helpful. Thanks

Re: MSA 2012i Multipath
Maybe the MPIO settings only support like this???
NIC-A Connect to Controller A Port0 & Port1
NIC-B Connect to Controller B Port0 & Port1
The user manual and configure simple was quiet unclearly.

As i know, if Controller B undetected Controller A heartbeat msg, it will do the following things:
1. Take over all Controller A's vDisk
2. Take over Controller-A0 & A1 iSCSI host IP to Controller-B0 & B1
