HBA SAN problem

hi
i have an esx server with two HBAs thats connected to a HP MSA 1000. Both HBAS are showing up in esx but only one in the HP ACU. i have done a  rescan on the controllers and changed the gbic but still no good. i have connected the HBA to a different gbic, did a rescan and still got nothing. it just wont show up in the HP ACU. any ideas here??

Where are you running the ACU from? Same host that you have ESX on or a seperate one? You can always enter the WWNN manually under selective storage presentation if you need to. If you unplug the HBA that is seen does the other one show up?

i cant unplug the HBA thats being seen as its our main ESX box. i am running the ACU on a windows server thats connected to the MSA.

where can i enter the WWN? i dont see any place for that. there are 8 HBA's listed, one is unknown, i dont know where its coming from. the only other buttons available are ok, cancel and back???

What I think is happening is that the MSA isn't seeing the second port because it is active/passive so the passive HBA doesn't advertise itself - see http://forums13.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1234456139740+28353475&threadId=900130 for similar problems. Swapping it onto the active controller might show it.

On second thoughts I don't think you can add unknown host using the ACU, I can't see how to do it in the ACU user guide. I mainly use the serial line CLI.

Adding a host WWPN is straight forwards using the MSA1000 CLI, it's just "add connection <ConnectionName> <wwpn=xxxxxxxx-xxxxxxxx>" and you can delete the unknown connection with "delete connection <name>". - see host connection commands in http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01183955/c01183955.pdf.

<time to find that serial cable, if you have Brocade switches be careful not to use that serial cable since it plugs in but isn't wired the same.>

I don't think there is a username/password. Are you plugged into a switch module at the back rather than the controller at the front maybe?

mikeleahyAuthor Commented:
yeah i was connected via the back. if i plug it into the front how do i connect? hyperterminal?

mikeleahyAuthor Commented:
is it an rj 45 connection in front. does the <connection name> matter. if i add it there will it show up then in the ACU?? can i give it access to luns via the CLI

andyalderSaggar makers bottom knockerCommented:
Hyperterm 19200,8,none,1,none (see PDF above page 14). However if you had the serial cable at the back and you could type and see output I think you have the Brocade cable.

andyalderSaggar makers bottom knockerCommented:
Yes, either of the RJ45s at the front. Connection name is whaever you want to call it. You can do everything with the CLI; pure VMware configs often have to use serial cable since no access to ACU.

i have the serial cable at the back but its looking for a username and password???

i tried connecting a console cable to the front port but the rj45 wont go in, the port seems a little too small

andyalderSaggar makers bottom knockerCommented:
It's either admin/password or root/fivranne but you are connected to the Brocade switch at the back. It's a different cable that goes in the front. I managed to force the Brocade cable into the controller at the front but it did take a bit of a push and it didn't work anyway.

so can i not do what i need to do by connecting to the switch at the back??
0
 
andyalderSaggar makers bottom knockerCommented:
No. The switch doesn't talk to the controller at anything other than a fibre channel level. It's just like a normal 1U external rackmount switch in that respect.

so what kind of cable do i need to buy to get into the connection at the front?
0
 
andyalderSaggar makers bottom knockerCommented:
The spare part number is in that PDF I posted. They have always been supplied so you probably have it somewhere. It looks very similar to the one you have except it's a different shade of grey.

The correct cable goes in quite easily.
