Swapping port area ids – HP Brocade 4Gb SAN Switch for HP BladeSystem p-Class User Manual

Page 217

Fabric OS 5.0.0 procedures user guide 217

Remove the device entries for the fabric you are migrating. For example, if the HBA for that fabric is

fcs0, issue the command:

rmdev -Rdl fcs0

Connect to each switch in the fabric.

Issue the

switchdisable

command.

Issue the

configure

command and change the Core Switch PID Format to 1.

10.

Issue the

configenable [effective_zone_configuration]

command. For example:

configenable my_config

11.

Issue the

switchenable

command. Enable the core switches first, then the edges.

12.

Rebuild the device entries for the affected fabric using the

cfgmgr

command. For example:

cfgmgr –v

This command may take several minutes to complete.

13.

If you are not using multipathing software, vary on the disk volume groups. The format is

varyonvg volume_group_name

. For example:

varyonvg datavg

14.

If you are not using multipathing software, mount all devices again and restart I/O. For example:

mount /mnt/jbod

15.

If you are using multipathing software, reenable the affected path.

16.

Repeat for all fabrics.

Swapping port area IDs

If a device that uses port binding is connected to a port that fails, you can use port swapping to make

another physical port use the same PID as the failed port. The device can then be plugged into the new

port without the need to reboot the device.

Use the following procedure to swap the port area IDs of two physical switch ports. In order to swap port

area IDs, the port swap feature must be enabled, and both switch ports must be disabled. The swapped

area IDs for the two ports remain persistent across reboots, power cycles, and failovers.

Swap area IDs for a pair of switch ports as follows:

Connect to the switch and log in as admin.

Enable the port swap feature:

portswapenable

For the HP StorageWorks SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, and SAN

Switch 4/32: issue the following commands:

portdisable port1

portdisable port2

For the Core Switch 2/64 and SAN Director 2/128: issue the following commands:

portdisable slot/port1

portdisable slot/port2
