An LU group capacity threshold can be specified on the LUGROUP, PRTGROUP, and default LU group statements. If specified, Telnet will check the number of LUs used in the group when an LU is assigned from the group. A message is issued when the group's in-use LU count is at or above the specified percentage of the total. After the message is issued, no other message is issued until the in-use count has dropped below the threshold by 10% of the total. For example, an LU group has 200 LUs with a capacity threshold of 80%. When the 160th LU is assigned, EZZ6007I is issued. Ten percent of the total in the group is 20. Therefore, after the number of in-use LUs has dropped to 140 or lower, another warning message will be issued when the in-use count rises to 160 again. If multiple LU groups have the same LU name, the only LU group checked is the group from which the LU is assigned to the client. The other LU groups might go over their capacity limits, but notification will not be issued until an LU is taken from the group. Below are examples for setting the capacity warning.
LUGROUP LUGRP1,80% TCPLU000..TCPLUF9F..FFFFFXNX
PRTGROUP PRTGRP1,60% TCPRT000..TCPRTFFF..FFFFFXXX
DEFAULTLUS ,75% LU000000..LU999999..FFNNNNNN
DEFAULTPRTSPEC ,90% PRTDEFS1..PRTDEFS9Capacity checking cannot be done for LU groups that are defined as LU name exits. During VARY TCPIP,tnproc,OBEYFILE command processing, all LU groups are checked for in-use LU counts and a capacity warning message is issued if needed.
