HBA card installation

[Yvonne Chan]

Why after installing a 2nd HBA card, my server cannot detect the disk space of the disk array on Storagetek? While it can detect the hardware path to it? Also when I use sam, it will show me 7 hardware path to the storagetek disk array. While my existing HBA card shows only 1 hardware path to the disk array.

Hi,

Once the hardware path has been recognised
you still need to create the actual device
files. This should create the files.

# ioscan -fn
# cd /dev
# insf -e
# ioscan -fn >/tmp/wrk

Check the file for the devices.

A reboot will effectively have done exactly the same as the suggestion above.

(hopefully you didn't add a card with power on - unless using rad or something like that)

The results of ioscan -fnk

and then the results of ioscan -fn would be interesting to see.

Although I presume that you need to install the card driver into the kernel.

You should have this info in you HBA docs.

kmtune may give you info on what drivers are installed, and you can install them via SAM > Kernel section.

Later,
Bill

I had done ioscan -fnk, ioscan -fn and also a reboot but still not able to see the diskinfo of my disk array via my 2nd HBA card.

Is there any other settings I should do? Like the drivers, patches, firmware.

[Bill McNAMARA_1]

Can you post up the output of the ioscan -fnk

It's not drivers since it works on one side...

It's more than likely a config on the device itself.. or something like conflicting scsi ids or cables.

Are there any other devices physically connected on the same bus?

Have you checked to see if you're using the latest version of the HBA drivers?

I know I had trouble with an N4000 and dual A5158A cards. Part of the problem was that I needed to attach to a SAN fabric which my early set of drivers did not support.

Currently, when I run "swlist A5158A" I get the following:

# A5158A B.11.00.10 PCI Tachyon TL/TS Fibre Channel
A5158A.FC-TACHYON-TL B.11.00.10 PCI Tachyon TL/TS/XL2 Fibre Channel

There maybe later versions, but this version works so far.

Hope that helps.

Thanks guys for your help. I had managed to get both HP and StorageTek engineers down to solve the problem. It was due to StorageTek that needs to configure the LUN to recongise the new HBA world wide number (WWN).
