IBM Certification Study Guide  AIX HACMP

  • 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

).

  • 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)

.

  • 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

.
