Hi,
I have one server (A400-44) with this target,
# ioscan -fnCfc
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
fc 0 0/2/0/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter
/dev/td0
and I have buy another one P/N A6826A (dual port) , to change it.
I have two vgs in the system (vg00 and vg01), and I have I have internal disc and fibre disc in these vgs (vg00 and vg01).
I don't know what I will have to do when I change the fibre, I suposed the discs will be change their cXtYdZ.
Could anyone help me?
Thanks a lot of!
Carme.
Users are not too bad ;-)

Re: change FC with discs in vg00 and vg01
What do you want ?
your question is not clear.
vg00 on --- internal disk
vg01 on --- internal disk
You can create map file.

Re: change FC with discs in vg00 and vg01
Hello Torca,
Usually each server will have 2 Fiber Cards ( 2 HBAs) fo redundancy.
ioscan -fnkCfc (this will show 2 of your FC HBAs)
fcmsutil /dev/fcd0 (or /dev/td0)
fcmsutil /dev/fcd1 ( or /dev/td1)
will show status as ONLINE.
you also need to configure on the SAN-SWITCH for zoning information.

Hi
This involves two procedures The 1st procedure should be done in LVM maintenance mode.
- boot in maintenance mode (-lm)
- vgexport -m vg00.map vg00
- ioscan
- insf -e
- locate the new device file name for system disk. Assuming this name is now /dev/dsk/c3t0d0 ...
- mkdir /dev/vg00
- mknod /dev/vg00/group c 64 0x000000
- vgimport -m vg00.map vg00 /dev/dsk/c3t0d0s2
- vgchange -a y vg00
- mountall (errors on other vg than vg00, but doesn't matter)
- su - root
- lvlnboot -R (check with lvlnboot -v)
- setboot -p HardwarePathOfSystemDisk (can get it with lssf /dev/dsk/c3t0d0)
- sync;sync;reboot -r
This is the 2nd procedure for non O/S disks - See the bottom of the thread. Ignore the top.

This is the same procedure, expanded to include every command. I used this in a EMC disk array migratation.
1)shutdown all databases on the system if SAP then have SAP shut them down
2)make a copy of the bdf bdf > /root/asap#.bdf
3)do an ioscan ├в fnC tape and look for any HP Ultrium drives
4)make map file vgexport ├в p ├в s ├в m /root/mapfile.map (volume group name) There may be more than 1 volume group per system.
5)Make sure maestro is shutdown on the system /sbin/init.d/maestro stop
6)Fuser ├в cu /filesystem if nothing shows up skip step 8
7)Fuser ├в cuk /filesystem
8)Unmount all file systems umount ├в a
9)Do a bdf and make sure you only see vg00
10)Do an ll /dev/*/group >
/root/major_numbers
11)Vgexport the other volume group/groups
12)Do a mkdir on all volume groups (mkdir /dev/(name)
13)Do a mknod on all volume groups using original numbers and names (mknod /dev/name/group c 64 0x0#0000)
16)Reboot the system shutdown ├в r now
17)Once the system comes up make sure you can see the "NEW" disks with an ioscan ├в fnC disk
NOTE: HERE is where the cables were changed from one array to the other, causing new device paths / pv names to be generated.
18)If you can not see the disks do an insf ├в e 2 times then try the ioscan ├в fnC disk again if you see the disks continue
NOTE: If you have EMC Power Path the 19, 20
19)Do a powermt config
20)Do a powermt display check serial numbers
21)ow do a vgimport ├в s ├в m /root/mapfile.map (volume group name) for each volume group
22)If the volume group imports then do a vgchange ├в a y (volume group name) (not done on Service Guarded systems)
23)Once the volume group is activated we can now run a mount ├в a on the system
24)Verify the new bdf with the old one that was saved in /root/asap#.bdf
25)Have either DBA or SAP start the databases and check them out.
26)Verify that any systems that had tape drives are now visible ioscan ├в fnC tape
8)Do an exportfs ├в a
