You can write your MKSYSB over NFS to another system. You can boot from that image and restore if over the network if you set up a NIM master.
NIM=network installation manager. This is included in the AIX software. - smitty nim

The script is scheduled with crontab and executes "mksysb -i -X /dev/rmt0".

nfs3_max_transfer_size
nfs3_max_transfer_size(5) File Formats Manual nfs3_max_transfer_size(5)
NAME
nfs3_max_transfer_size - control the data portion size of a NFS version 3 read, write, readdir, or readdirplus request
VALUES
Failsafe
Default
Allowed values
Recommended values
A warning will be issued at runtime if the tunable is set to a value greater than 1048576 since this is outside the tested limits. This is
not a serious warning but just an information message for the administrator.
DESCRIPTION
controls the maximum size of the data portion of a NFS version 3 read, write, readdir, or readdirplus request. This parameter controls both
the maximum size of a request that the server returns as well as the maximum size of a request that the client generates.
Who Is Expected to Change This Tunable?
Distributed file system administrators should examine this value if they want to decrease or increase the default size of a NFS packet.
Restrictions on Changing
The tunable is dynamic; however, the transfer size for a file system is set when the file system is mounted. To affect a particular file
system, unmount and mount the file system after changing this parameter.
The actual NFS version 3 transfer size is controlled by these tunable parameters: and The actual transfer size will depend on the tunable
with the smallest value. For NFS version 3 TCP traffic increase and to the same value to increase the transfer size. To decrease the trans-
fer size, just changing is sufficient.
When Should the Value of This Tunable Be Raised?
An increase in the transfer size will result in fewer requests to the NFS server at the expense of system resources on both the NFS client
and NFS server.
What Are the Side Effects of Raising the Value?
Setting the limit too large might result in errors from UDP and communication problems between the client and the server.
When Should the Value of This Tunable Be Lowered?
In the event of NFS communication failures, the value should be changed back to the default value.
What Are the Side Effects of Lowering the Value?
An increase in NFS version 3 network traffic caused by an increase in the number of I/O requests.

All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of

Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
