Customizing the chassis name
Beginning with Fabric OS 4.4.x, it is recommended that you customize the chassis name for each switch.
Some system logs identify switches by chassis names, so if you assign meaningful chassis names in
addition to meaningful switch names, logs will be more useful.
How to change the chassis name
1. Connect to the switch and log in as admin.
2. Enter the
chassisName
command at the command line, using the following syntax:
where newname is the new name for the chassis.
Chassis names can be from 1 to 15 characters long, must begin with a letter, and can contain letters,
numbers, or the underscore character. It is not necessary to use the quotation marks.
3. Record the new chassis name for future reference.
Working with domain IDs
Although domain IDs are assigned dynamically when a switch is enabled, you can reset them manually so
that you can control the ID number or to resolve a domain ID conflict when you merge fabrics.
If a switch already has a domain ID when it is enabled, and that domain ID conflicts with a switch already
in the fabric, the conflict is automatically resolved. The process can take several seconds, during which time
traffic is delayed.
The default domain ID for HP StorageWorks switches is 1.
The default domain ID applies to the logical switches in the SAN Director 2/128 that are configured for
two domains. To prevent domain conflict, you can either disable one of the switches until the other is
connected to the fabric, then re-enable the switches so that unique domain IDs are automatically assigned,
or you can use the procedure ” How to set the domain ID ” on page 38 to make the domain IDs unique
before connecting the logical switches to the fabric.
CAUTION: On switches running Fabric OS 4.x and later, do not use domain ID 0, which is reserved for
another purpose. The use of this domain ID can cause the switch to reboot continuously.
Avoid changing the domain ID on the FCS in secure mode. To minimize down time, change the domain
IDs on the other switches in the secure fabric.
