Re: System names.

Hello Rob
(this is my first message on this list, so hopefully it will work)


I am not talking about individual lpar names, or anything you normally see
in IBM i (like in DSPNETA) but I'm talking about the whole system
containing all the lpars.

On my HMC I have these systems:
Server-8286-41A-SN214403V
Server-8286-41A-SN214405V
Server-8286-42A-SN21443BV
Each system contains multiple lpars.  For example the 42A may have GDIHQ1,
GDISYS1, GDWEB1, MAIL1, etc; the 41A-3V may have GDIHQ2, GDISYS2, MAIL2
and the 41A-5V may have MAIL3, GDWEB3...
>From the command line on the HMC I can list by these names, or by
type-model*serial#.  For example these commands both work:
lssyscfg -r lpar -m Server-8286-41A-SN214403V -F name,lpar_id,state
lssyscfg -r lpar -m 8286-41A*214403V -F name,lpar_id,state

The "Server..." names were from defaults.  I am thinking of changing them
to something more meaningful.  In my case RACK1, RACK2, RACK3.  It's
actually really simple to do.
I can't think of any negative ramifications of doing so.  "Call home"
won't confuse IBM, will it?  Hopefully it's not keyed off of this.
I may have to adjust my downtime instructions.
We have changed the name of all the servers in our datacenter with the same goal as you have. 
Call Home makes use of the type/model/serial number so no issue about this.
The unique issue I am thinking to is about tools that you may use from somewhere (like we do from an IBM i partition) to connect to the HMCs, which expect to find the old server's name (we have some tools running on an IBMi partition which are based on the server name set in DB2 tables), or documentation which refer to this name.
The naming convention may include the serial number, a reference to the location in the datacenter... Any valuable information which fits your needs.
