fcmsutil replace_dsk?? Please help!

Tim Medford — Wed, 20 Apr 2005 14:49:51 GMT

Greetings all. I am in the process of switching from one physical storage array to another, on an rp5470 running hpux 11.11. I have dual fibre channel cards.

I have these device files:
/dev/dsk/c14t0d0 (td0) 0/1/0/0
/dev/dsk/c15t0d0 (td1) 0/3/0/0

/dev/dsk/c14t0d1 (td0) 0/1/0/0
/dev/dsk/c15t0d1 (td1) 0/3/0/0

I have done vgreduce to all volume groups so that everything is channeled through c14t0dx and then I disabled the inactive card using fcmsutil /dev/td1 disable.

I unplugged the fibre from card at address 0/3/0/0 and plugged the new cable into it.

When I now re-enable the card at /dev/td1 and ran insf -e but the device files and hardware addresses look the same?? I'm getting a bunch of errors in the syslog saying use fcmsutil with the replace_dsk option.

I was expecting to see the new luns with new device file names.

Can you tell me which step(s) I missed?

Thanks!

You need to run /opt/fcms/bin/fcmsutil /dev/td(n) replace_dsk nportid command.

you will see nportid in syslog file.

Thanks Uday.

This is what is in the syslog, so it looks like the port ID is 0xef? This will not harm any of the luns/devices going through the other card at /dev/td0??

0xef is looks like your nport id.
Use replace_dsk command as mentioned above.

Have a look at this doc for more information

As Uday stated above use the fcmsutil replace_dsk to get rid of the syslog errors, but make sure you do it down both paths,

fcmsutil /dev/td0 replace_dsk 0xef

fcmsutil /dev/td1 replace_dsk 0xef

Thanks everyone, the problem has been resolved.

Thanks to the miracle of ISEE a support engineer called right as I was getting ready to do this and we talked through the whole process.
