md3000i problems

Hi,

I'm having some problems getting a PE2950 connect to MD3000i. The software adapter lists no targets (vm-iscsi.jpg), and I have tried rescaning several times even restarting twice.

ESX Server is version 3.50 82663 (Diden't work before upgrade to update 1)

Firewall is opened to allow Software iSCSI Client 3260(TCP).

/var/log/vmkernel shows:

Apr 12 15:23:18 vmkernel: 0:00:20:07.421 cpu5:1041)SCSI: 861: GetInfo for adapter vmhba32, , max_vports=0, vports_inuse=0, linktype=0, state=0, failreason=0, rv=-1, sts=bad001f

I can ping all four MD3000i iscsi host ports form the esx server (192.168.130.101, 192.168.130.102, 192.168.131.101, 192.168.131.102). ESX Network configuration can be viewed in the attachment (vm-network.jpg). The physical network is configured as shown in attachment (physical-network.jpg) with no vlan.

The iSCSI Initiator (vmhba32) is set to Dynamic Discovery on 192.168.130.101:3260 and 192.168.131.101:326 with no CHAP on either side.

Any help/suggestions would be greatly appreciated!

What is name of your iscsi initiator?

I can see iqn-

the - is not correct at that place.

The iqn must have the right format (with dot i.e iqn.2000-05.xxx:xxx check there:

This is a Dell issue...there is a rather long thread already posted here which describes the problem and the solution. Search for "md3000i" and you'll find it. Basically, the MD3000i doesn't support the iSCSI standard for naming, so you have to go back in and make sure the name is less than 31 characters.

Indeed - this is part of why its not certified.

Thanks for the reply. I changed the name to 18 characters on MD3000i, and esx server, but still no luck. Same error messages!

Well that is definitely supported with Esx 3.5.

Why don't you want to start with only one path to md3000i - and check the right fw version on your md3000i to run with Esx (I don't know the version no.).

Should be the both Gbit switches connected together? I'm not sure here.

I removed one of the vswitch, and took the physical cabling down to one path. I now have one pingable path down to the MD3000i. I also upgraded to the newest firmware version for the MD3000i.

Still doesn't work.

Just to clear something: Does the ethernet management ports need to be on my iSCSI network? I got both connected to my lan for management.

I saw that post earlier, and checked for the common mistakes. The LUN is around 1TB (which is total disk space in the md). All my initiator names or aliases are around 20 characters(less then 30), and the firewall is open for iscsi.

I ran the vmkiscsid in debug mode:

Seems like the md3000i is closing the connection, but im running out of ideas.

Your right. My iscsi initiator diden't follow the naming standards.

Works like a charm now.

Thanks for your time and help!

I am having a similar problem with my MD3000i... how can I set my iSCSI adapter names back to the correct standard? iqn-xxxx etc.

I've tried disabling the iscsi adapter both via the GUI and console.

I have another server which is working fine connected to the MD3000i so its something with this particular install.
