zcom 00169: Not enough memory for Buffer-Pool size of <#> bytes
Buffer-Pool size reduced to <#> bytes.
Explanation: This message is logged during ZCOM subsystem
startup if the LDM finds the specified Buffer-Pool size
in the ttgen configuration file is larger than what the
kernel can accommodate.
When kernel memory is not sufficient to meet the ttgen
configuration, the memory reserved for Buffer-Pool is
reduced to allow system startup. The other ZCOM
tables are not affected. The user should make sure the
reduced buffer-pool size can still allow normal
operations.
Action: The ttgen configuration file should be reviewed to see
whether unnecessary tables can be reduced (e.g. too
many program or terminal ZLUs defined, too many
unused node entries). Otherwise, should consider
increasing the kernel memory for ZCOM. The total size
of the ZCOM memory in kernel is configurable, by the
zcom_mem_size tunable parameter (usually added to
/stand/system). See Appendix B for detailed
description.
zcom 00170: Buffer-Pool size set to <#> bytes.
Explanation: This message is logged during ZCOM system startup if
the LDM finds the specified Buffer-Pool size in the
ttgen configuration file is smaller than what the kernel
can accommodate. The LDM will allocate more memory
to the Buffer-Pool, so as to use up all the kernel
memory reserved for the ZCOM system.
Action: The user should make sure the intended use of memory
is correct. The ‘extra’ memory is not because of
incorrect ttgen configuration. If it is not desirable to
use a large Buffer-Pool (e.g. in a small testing system
with only limited memory), the total size of the ZCOM
memory in kernel is configurable through the
zcom_mem_size tunable parameter (usually added to
/stand/system). See Appendix B for detailed
description.
