Detecting the Need for Additional Processes
To do so, issue an ADD PROCESS command. For example, to add a new initiator
process named FTI3 to the example configuration (see Example FTAM Configuration on
page 3-38), issue a command such as the following:
ADD PROCESS $AMGR.#FTAMI.FTI3, NAME $FTI3, COMNAME "FTMI3A" &
, CPU 2, BACKUPCPU 0, SWAP $OSI
This command adds the definition of a new FTAM initiator with the internal name
$AMGR.#FTAMI.FTI3 and the external Guardian name $FTI3 to the APLMGR MIB.
Issue the SCF START command to create the process and place it in the STARTED
state.
For a description of the PROCESS attributes used to configure initiator processes, see
Table 2-8, PROCESS Object Attributes—Run Options,
on page 2-18, and Table 2-9,
PROCESS Object Attributes—Management Options, on page 2-19.
Adding Responder Processes
If a responder process on your system has a workload that exceeds its capacity, you
might need to add one or more responder processes with the same address. Generally,
there are two statistics to monitor when deciding to add a responder process. If the
number of pending requests that remain pending without response are high (for instance,
if Measure shows that the responder is constantly waiting for disk I/O), you may need to
add another responder process. In addition, if the number of current associations almost
equals the maximum number of associations, you might want to add another process.
The number of current associations for a responder process is equal to the number of
subdevices for that responder for which the Opens value is 1; to find out this number,
issue the NAMES SU command and then issue a STATUS SU command for each named
subdevice. The maximum number of associations is displayed by the INFO PROCESS
command with the DETAIL option.
To do so, issue an ADD PROCESS command. For example, to add a new responder
process named FTR3 to the example configuration (see Example FTAM Configuration
on page 3-38), issue a command such as the following:
ADD PROCESS $AMGR.#FTAMR.FTR3, NAME $FTR3 &
, PROFILE $AMGR.#VFS.VFS1
, CPU 1, BACKUPCPU 0, SWAP $OSI
This command adds the definition of the new FTAM responder with the internal name
$AMGR.#FTAMR.FTR3 and the external Guardian name $FTR3 to the management
information base. Note that the VFS profile is the same profile used by the other
responder processes; therefore, this responder will have the same OSI address, and can
share the workload of the other two responder processes. Issue the SCF START
command to create the process and place it in the STARTED state.
For a description of the PROCESS attributes used to configure responder processes, see
Table 2-8, PROCESS Object Attributes—Run Options,
on page 2-18, and Table 2-9,
PROCESS Object Attributes—Management Options, on page 2-19.
