if you do not have load balancing turned on you will see the active standby avail avail. We just went through that here. Once load balancing is on then you'll see active active

Franky,

You might try the following to see if there is a problem with your HBA cards. The ioscan on fc will tell you whether your HBA cards are claimed.

# ioscan -fnC fc
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 0/3/0/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter
/dev/td0

/dev/td1
fc 2 0/7/0/0 td CLAIMED INTERFACE HP Tachyon TL/TS Fibre Channel Mass Storage Adapter

Then do a fcmsutil on the /dev/tdn;

# fcmsutil /dev/td1

This will tell you if the card is online or not. Something to get started by at least.

Thank for the inputs.
If that is ok, with everyone, then I'll close this posting.

Franky,

it was a really useful thread...
Thank's and Good Luck,

[Franky Leeuwerck_2]

Thanks for all your contributions.
I could learn a lot from you experts !

Franky,

I was hoping to see how you got on after you got commandview EVA (with or without SAN MA). I guess I'll have to keep an eye open for a new post.

Although the CV-EVA gui is pretty intuitive.

Good Luck.

[Franky Leeuwerck_2]

Hi Gavin,

Well, the host ( fibre-channel connected to the EVA) with the CommandView software is just not present there. And I need a reconfiguration of the volumegroups (currently 1 LUN presented of 250 GB as I learned in this thread ).
My local contact is checking with HP, if it is possible ( budget ) to have an HPCE come over and reconfigure the SAN ( instead of purchasing the CommandView setup ).

Thanks for your further concern.

That seems like a short-term solution to me.

In my view one of the big selling points of SANs is the ease with which you can present vdisks to hosts and move them to other hosts if need be, to do that you'll need commandview EVA.

That's just my opinion.

Cheers.
