Fiber card replacement

[balaji_vvv]

It looks like one of our redunant FC card failed and we are planning to replace this?
Our current setup is server connected to the switch and then to the storage?
Will replacing the FC card requries any configuration change on the switch (zoning)
or just replace FC?

The new card will have a new ID..

zoning and lun masking will need to be updated.

"how to" depends on your switches and arrays.

Thank you. The problem is i dont have access to the switch. Thanks for your reply though.

Hi,
>>Thank you. The problem is i dont have access to the switch.

Usually SA's are not having access to storage switches, after changing the FC card you need to ask the storage team to do the update you need to tell the new WWN no of the FC card.

If you provide the model of the switch we can aid in updating the zoning.

first verify that the card had failed.
you can verify by checking it in the OS side.
it has to have 4 or 8 paths depending on the EVA.
btw what is you OS?
if hpux then
ioscan -fnC fc
should show fc as claimed.

Hello,

There are multiple steps involved into this.

1. First be sure that the card is failed in the server side or any OS/driver issue using ioscan.
2. If you confirmed the card is failed, replace the card and get the new wwn number.
3. Now communicate with your storage team and know how they perform the zoning (port wise or WWN based). I believe, if it is port wised, you would not need to do any modifications anywhere at athe switch but you have to if it is WWN. Hope it helps you.

Thank you all for your replies. I'm very new to this environment. The OS is 11iv1 and server is rp4xxx series and its connected to virtual disk array via the switch (hp storage works san switch) through fp. I'm physically seeing the card okie (steady green) and also OS shows 2 fp card.
vmunix: td: claimed Tachyon XL2 Fibre Channel Mass Storage card at x/x/x/x
vmunix: td: claimed Tachyon XL2 Fibre Channel Mass Storage card at y/y/y/y
But the problem is only one is active as i'm getting message when the server reboots (scheduled)

syslog: CVSDM; INFORMATION Event Code=400; Description=542:BACKEND_LINK_DOWN_EH A disk interface has been down for longer than the time allowed for normal recovery. Array function will continue without use of this channel.
Still i didnt go in depth as its critical prod server and dont want to messup.

On the Fiber switch you need to login via the webpage and modify the zoning, update the zones containing the old HBA entry with the new one.

For the EVA array you need to login via command view and do the same.

( unless you are using some other software to manage your SAN. )

The switch is not in the network at all. (no lan connection)! I will check with HP i actually having issue with this fc card.
