Unable to see devices through SAN

[James Colby]

Hi All -

I have just converted one of my N-class server from a FC-AL directly connect to an EMC 3930. We are trying to convert it to SAN attached through an EMC connectrix. The guys from EMC have in and done all the zoning and stuff but we cannot see the disks. We have a Tachyon A5158A controller. I have loaded the B.11.00.10 patch for the A5158A tachyon controller. Is there anything else that I can look at? Thanks.

At the risk of asking the obvious,

Have you ran insf -e?

Hope this helps

Make sure that the connection from your machine to EMC boxes is OK.
Other thing is that make sure your tachyon driver is CLAIMED when you run ioscan -fn.

If you are still unable to see your drives, then may be EMC engineer can help you out.

Another thought, In addition to the driver softwware for the card, I also had to install PHKL_23939 (there may be a newer one). It is recommended to install the patch first, then the drivers, reboot recommended on the card software.

Hope this helps.

Hi,

After making sure you have connections to
your SAN, and you can see the WWN from
your switch, conceivably you should also
see your disks. A lot of the time you *will*
need to run 'ioscan-fn' to query the LUN's
that have been set up. Once you can see the
LUN's in your ioscan output, all you should
need to do is:

# cd /dev
# insf -e

Are you getting the link light on the HPA? I assume you are because you said zoning has been done. If zoning was done before you recieved a good conection you might want to re-check it.

You also said EMC has done the zoning which is of course needed but what about SDDR and Volume Logix? If this is a new EMC, has the volume logix database been created? Has vcmfind been ran on all the hosts?

Also after giving access to a HPA in Volume Logix did someone activate the new configuration and run the task?
