HP DL380p G8 + MSA 2040

[HserHK]

I am using DL380p G8 with one 4port 331FLR 1G NIC and one 2 port 530SFP+ 10G NIC, all of them are connecting to a MSA 2040 with iSCSI.

When I try to create MPIO on the server, it works, unless I reboot the server, the disk connected by 530SFP+ will be labeled as Disk -1 and all traffic will be go though 331FLR.

If the disk is connected with 530SFP+ only, it can works prefectly.

PS1: that 530SFP+ is connected to a swicth with one port only, for Hyper-V VM traffics and iSCSI connection.

PS2: two connections are in single VLAN.

Am I missing any step?

1. Use Broadcom Advanced Control Suite 4 to assign IP to 530SFP+ iSCSI Adapter
2. Create iSCSI connection by using Windows ISCSI Initiator
3. Tested the connection is works
4. Change HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mpio\Parameters\PDORemovePeriod to 300
5. In command prompt: mpclaim -n -i -d "HP      MSA 2040 SAN"
6. Create one more connection for 331FLR
7. Tested all connections are work
8. Reboot
9. The disk connected by 530SFP+ is labeled as Disk -1 and not working

Thanks

Although it is not recommended to use Multipath in ISCSI connections but you may try to make it work by following the link

Thank for your link, tested but no luck

Seems that if the 331FLR NIC is connected before the 530SFP+, 530SFP+ connection will be dropped.

An error is logged once reboot:

Device instance \Device\00000067 of \Device\MPIODisk1 was rejected because the maximum transfer length of the underlying adapter is too low.  The device will be accepted after a reboot.
