If the new system has new KGPSA adapters, the worldwide name-to-target
ID mapping has to be synchronized to remove the worldwide name for the
old KGPSA adapters and assign their target IDs to the new worldwide name.
To replace a cluster member system with a new member system that has
new KGPSA host bus adapters, follow these steps:
1.
Remove the member system from the cluster (that is, delete it from the
ASE membership). Make sure that it is gone.
2.
At the HSG80, delete the connection to the old member’s KGPSA
adapter. The old member’s KGPSA adapter must be deleted from all
HSG80 controllers to which it was attached.
3.
Install the new member system hardware and power up the system.
4.
Boot the member system to single-user mode:
>>>
boot -fl s
5.
Mount the file systems, set the root file system writable, and start the
network by entering the following commands:
#
/sbin/lsmbstartup
#
/sbin/bcheckrc
#
/sbin/init.d/inet start

Note
_____________________
You only have to execute
/sbin/lsmbstartup
if you are
using the Logical Storage Manager (LSM).
6.
On any other cluster member system, execute the
/usr/sbin/emxmgr
-t
command to determine the worldwide name of the new KGPSA host
bus adapter and the target ID of the KGPSA that is no longer on this
bus. Repeat for all new KGPSAs.
7.
Create a file that contains the worldwide name-to-target ID mapping
information obtained from the
emxmgr -t
displays. The target ID in
each entry will be the target ID of a KGPSA that is no longer in the
system. The port name and node name will be the worldwide name of
the new KGPSA to be assigned to that target ID. Each file entry could
could be entered in either of the following formats. See Chapter 3 for
more information.
emx1 7 1000-0000-C921-18A4 1000-0000-C921-18A4
{ 0, 7, 0x0010, 0x0000, 0x21C9, 0xA418, 0x0010, 0x0000, 0x21C9, 0xA418 }
8.
Modify the worldwide name-to-target ID mapping for the new devices
by executing the
emxmgr
utility using the file you just created (for
instance, call the file
/tmp/new-system-remapping
):
