You can't as it doesn't exist on 11.23. It was a new tunable added in 11.31:

â ¢Tunables msgmax, msgssz, msgmap, msgseg are obsolete in HP-UX 11i v3.

â ¢New dynamic tunable msgmbs is added, which indicates the maximum (in megabytes) kernel memory to be used for messages waiting to be received. This new tunable replaces the function of the obsolete msgssz and msgseg tunables. Lowering the tunable value has no effect on any active messages, even if the new tunable value is less than the total number of message bytes currently enqueued. However, no new messages may be queued until the total number of bytes falls below the setting of msgmbs.
