soft zoning and change eva8000, host the port

[Carlos F. Baladrón]

First of all: we are using soft zoning (zone information based on WWN). In environment with servers hpux 11.23
 
What would happen in the fabric if we change a host fibre from the port 5 of a switch to the port 10, and move the EVA8000 fibres which are in ports 7,8,9,10 of the FC switch to ports 20,21,22,23?
In the servers, change the device files? change the hardware path ?

[Torsten.]

For hp-ux up to 11.23 the port on the switch where the storage is connected is part of the hardware path.

Different port = different device files.

In order to change the ports, consider to vgexport the volume groups, change the ports and use vgimport to import your VGs.

Yes it will change the Device files and the HW Path..

Hope the below link will give some valuable information ....

Example:

disk 295 0/0/10/1/0/4/0.11.4.0.0.0.1 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c65t0d1 /dev/rdsk/c65t0d1


The important part is

11.4.0.0.0.1

where

11 = switch domain ID
4 = port (connects the EVA)
1 = LUN 1

In this example the "4" would be changed, hence the system creates new device files.

So, yes affect changes eva8000 port
Changes in the port host would not affect

Just for info: modern switches _can_ program their engine to do 'hard zoning', even if the zoning definition uses all WWNs:
FCSW02:admin> portzoneshow
PORT: 0 (0) F-Port Enforcement: HARD WWN defaultHard: 0 IFID: 0x43020000
PORT: 1 (1) F-Port Enforcement: HARD WWN defaultHard: 0 IFID: 0x43020001

Hi,

Yes When u change the host fiber cable from port 5 to 10.

And move the fibers in ports of the FC seitch the device file port connect with would be change.

Due to Diffrent Ports will provide diffrent device files.

In this condation before changing the port

Please do the vgexport of all vgs

vgexport -v -p -s -m /tmp/vg01.map vg01

After change the ports do vgimport for your all vgs.

vgimport


Thanks
