EVA 5000 New Install + HP-UX 11.0

[Dave La Mar]

Here is the scenario:
1. (2) RP7400 servers.
2. (1) L-Class server.
3. O/S is HP-UX 11.0 on each.
4. Each server has current storage to an XP512 and multiple applications running on each.
5. Just received an EVA 5000.
6. All patches for the EVA attaching to each of the three servers have been applied.

The Pertinents/Question(s):
1. We have the HP Business partner onsite configuring the EVA, attaching the fibre channels, and presenting the storage to the servers.
2. Storage has been presented to one of the servers only.
3. The server mentioned does not see the disk(s) presented.
4. Business partner has had us perform ioscans and we have done insf(s) as well.
5. The disks are still not seen by the server.
6. There are new HSV entries in the ioscan but no disks are associated.
7. Business partner says a reboot is now required.
8. Can anyone confirm or deny a reboot is required from this point for the server to recognize the storage?
9. Has anyone a solution outside of a reboot?

Any and all input appreciated.

Hi,

as far as I know, if you installed Secure Path before a LUN has been presented then you need to reboot. Secure Path is in inactive state and ioscan does not work.

Mario.

Mario -
Are you saying we should have installed secure path after presenting the storage?
??? After installing secure path, I believe a reboot was required.
Thus, I gather you are saying a reboot would have been required in any respect.
Our concern is that these are production boxes.
A reboot takes some co-ordination with the people affected by the running applications in order to find a window for the reboot.
I am just having a hard time understanding the need for a reboot. There must be a way to see the storage without a reboot.
Thanks for the insight, still looking for a hard confirmation that we are doomed for a reboot.

It does not matter, SecurePath or not, you will need to reboot your server for it to "see" any freshly presented LUN from your EVA. Subsequent presentation will no longer require a reboot.

I advice you though to use SecurePath so you'll have a fully supported EVA. Of course you can always hook up via a single HBA and without SecurePath and it will still be supported.

Just an update.
I have spoken with a storage expert for HP. He states the problem is with the FC card driver, a small bug not yet resolved.
Although a reboot will re-initialize the HBA we are going to attempt a reset with fcmsutil this afternoon.
I will post results following that, (as well as assign points).

Thanks for the input.

Regardless and I doubt a bug on the FC-HBA driver, you will need to reboot for your server to "see" your initial presented VDISK/LUN.

What FC-HBA are you using anyway?

[Dave La Mar]

Well, the jury returned and the verdict is death by rebooting.
Nice thought on the reset but it did not resolve the problem.
Thanks for the correct input.
