Task 9: Perform the Guided Procedure for
Configuring a ServerNet Node
Using SCF to Configure Expand-Over-ServerNet Line-
Handler Processes
HP recommends that you configure line-handler processes using the guided procedure
for configuring a ServerNet node. The guided procedure can automatically generate
line-handler processes for you, if desired. However, you can configure these processes
manually by using SCF.
Line-Handler Processes Required for Clustering
Every system in a ServerNet cluster must have an Expand-over-ServerNet line-handler
process for every other system in the ServerNet cluster. Therefore, when you add a
system to a ServerNet cluster, you must configure multiple line-handler processes:
For example, if you have a ServerNet cluster consisting of three nodes, and you want
to add a fourth node, you must configure a total of six line-handler processes—three
on the system you are adding and one on each of the three current nodes of the
ServerNet cluster. In addition, every line-handler process must be given a unique
name.
Example
The following SCF example shows recommended modifier values for an Expand-over-
ServerNet line-handler process:
>SCF
>ADD DEVICE $ZZWAN.#SC006, CPU 2, ALTCPU 5, PROFILE PEXPSSN, &
>IOPOBJECT LHOBJ, TYPE (63, 4), ASSOCIATEDEV $ZZSCL, &
>NEXTSYS 123, RSIZE 0, SPEEDK SNET, COMPRESS_OFF, &
>PATHBLOCKBYTES 0, PATHPACKETBYTES 4095
On . . . You must configure . . .
The system you are adding Line-handler processes for all the other
systems in the ServerNet cluster
All other systems in the ServerNet cluster A line-handler process for the system you are
adding
Note. To log on to a system other than the one where your current TACL process is running,
you must first start a remote TACL process in that system. You must also set up remote
passwords between the local system and the remote system. You do this using the
REMOTEPASSWORD command. For information about configuring remote passwords, refer
to the Guardian User’s Guide.
