Table 144 on page 206 shows the EC history of the microcode where you write the EC and link levels of
the microcode, the date, and the device serial number. You write the values here when you install the
device, replace the drive canister, or update the canister to a new microcode level.

Copy Table 145 on page 207, and use it as a worksheet to keep a record of the address history of each
device. If a replacement of the drive canister is necessary, the service representative has a permanent
record of the drive serial number and the port and node names.
Note:
1. Ensure that the drive is offline. See “Set Offline menu” on page 99.
2. If you alter any name, you must save or alter all the names. For example, if you alter the Node 0 Name
only, you have to at least save Node 0, Port 0 and Port 1.
3. For 3592, fibre node names and port names are in the range 5005076302XXXXXX.
4. Ensure that the port/node names are unique. If two drives in an installation have the same WWID, only
one is recognized by the host or the controller.
Every time a drive canister is replaced, record the complete row of entries.
1
The customer serial number of the device.
2
Worldwide Node 0 name.
3
Worldwide Node 1 name.
4
Worldwide Port 0 name.
5
Worldwide Port 1 name.
