HPE Primera FC and iSCSI HOSTs simultaneously

[vesix]

Hello,

I just want to ask if there is a special procedure of configuration if FC HBA and iSCSI HBA are used on the same PRIMERA box A630. There is used the latest version 4.2.2 and we use 2 x FC ports for HOST connection (it's OK and it works well) and 4 x iSCSI ports which should also be used for HOST connection (of course the every single HOST will used FC or iSCSI connection not both). The issue is that the iSCSI ports are still in state Free and no way to established iSCSI session from Windows HOST. On the Windows HOST there is event like target port is not responding (port is default 3260). ICMP PING from both sides are OK. Any hint.

Thanks in advance

Hello Vesix,

Have you tried editing and enabling the port?

Systems -> Ports -> Select the iSCSI port -> Options under Actions menu

Hello,

Yes, I've tried all possible ways to disable and enable again and even tried to Reload Firmware on one specific iSCSI port. The result is still the same. Port is free and no way to get it accessible from the HOST.

Have a good day

Hello Marcel,

The state 'free' indicates the hosts does not login to the port. So it is considered a symptom, not the cause.

Are the ports showing the correct iSCSI name? (showport -iscsiname <port>). Also a 'showport -iscsi' displays the right IP configurations?

What is the MTU settings? Does that match with the host? 

And is the issue only with Windows hosts? 

[vesix]

Hello,

So far we have only tried the iSCSI connection from Windows server (we have no direct connection to customer's HOST systems so it's hard to troubleshoot). Otherwise according to customer there is default MTU value (1500). From the iSCSI port configuration all seems to be OK.
There is error event generated (see below) at the Windows server if "Discover Target" is started from iSCSI initiator. If we try the same to any other storage system all is OK.

Any idea what is wrong?

Thanks in advance

Marcel

Error event from Windows:
The initiator could not send an iSCSI PDU
Target failed to respond in time for a login request.

Hi vesix,

this is because iSCSI for Windows is (not yet) Supported on Primera.

I expect this comes with the 4.3 release in a few weeks.

You can't do anything to get it worked until it is supported.

Cali

See SPOCK:

https://h20272.www2.hpe.com/spock2/cont/configsetresultview?repositoryId=774883&navId=0&source=Constraint

[John88]

Spock has a section that shows support for PRIMERA OS 4.1 and 4.2 for iscsi for Windows 2016 and 2019 under addtional configuration sets. I also cannot get iscsi going for 4.2.  

[Cali]

I don't see Windows iSCSI Support for 4.2, but you can Update to 4.3.1.

As of today it seems not to be Auto Downloaded by the Storage, but you can get it here:
