6.1.2 System Parameters
• Type
date
on all nodes to check that all the nodes in the cluster are
running with their clocks on the same time.
• Ensure that the number of user licenses has been correctly set
(lslicense
).
• Check high water mark and other system settings (
smitty chgsys)
.
• Type
sysdumpdev -l
and
sysdumpdev -e
to ensure that the dump space is
correctly set and that the primary dump device (
lslv hd7
) is large enough
to accomodate a dump.
• Check that applications to be controlled by HACMP are not started here,
and that extraneous processes which might interfere with HACMP and/or
dominate system resources are not started (
more /etc/inittab)
.
• Check list of cron jobs (
crontab -l
).
6.1.3 Process State
• Check the paging space usage by issuing
lsps -a
.
• Look for all expected processes with
ps -ef | more
.
• Check that the run queue is < 5 and that the CPU usage is at an
acceptable level (
vmstat 2 5)
.
6.1.4 Network State
• Type for example
ifconfig lo0
,
ifconfig en0
and
ifconfig en1
to check the
network adapter configuration, if you are using ethernet adapters. For
other types of adapters, use the appropriate device name.
• To check the configuration of an SP Switch adapter, type:
/usr/lpp/ssp/css/ifconfig css0.
• Use
netstat -i
or
netstat -in
to show the network configuration of the
node.
• To check the alternate MAC address, issue
netstat -v ent0 | more
.
• Look at mbufs sizing relative to requests for memory denied (
netstat -m |
more)
.
• Type
netstat -r
or
netstat -rAn
to ensure that there are valid routes to the
other cluster node interfaces and to clients.
• Run
no -a | more
and look at the setting of
ipforwarding
and
ipsendredirects
.
