Steps to create a Syctl application Task :- User siju (kerberos principal siju.adm) should get the permission to start a subsystem by executing the command substart. Permission should not be given to other users. 1)

Create the client application substart in /usr/bin directory of cws with following contents if [ $# -gt 2 ] then echo "Arguments exceed the limit" exit 1 fi /usr/lpp/ssp/bin/hostlist -n $1 | /usr/bin/sysctl -c - substart_proc $2 In the above script if condition will check for the number of arguments and execute procedure on corresponding host

2)

Change the mode to executable chmod 755 /usr/bin/substart

3)

Create server application substart.tcl with a procedure substart_proc with following contents create proc substart_proc {SubSystem} AUTH { global SCUSER if [ aclcheck -f /etc/substart.acl $SCUSER ] { exec /etc/substart.srv $SubSystem return } } if condition in the above example checks for kerberos user in the acl file /etc/substart.acl If the condition is true it execute the command /etc/substart.srv with arguments passed by substart command

4)

Create the script substart.srv with following contents startsrc -s $2 This script execute the command startsrc with the argument passed by the substart command

5)

Change the mode to executable chmod 755 /etc/substart.srv

6)

Create acl file substart.acl with the entry for user siju

#acl# _PRINCIPAL siju.adm@CWS 7)

Add the application to the sysctl by adding following line to sysctl.conf file include /etc/substart.tcl

8)

Distribute the files to all nodes pcp -av /usr/bin/substart pcp -av /etc/substart.tcl pcp -av /etc/substart.srv pcp -av /etc/substart.acl pcp -av /etc/sysctl.conf

9)

Restart the sysctld daemon to get the new information on cws and on all nodes

10)

Get the kerberos ticket for user siju and execute following command substart 3 lpd This should start the lpd daemon on node 3

11)

Try the above command with any other kerberos ticket. Result should be negative

Run /usr/sbin/cluster/clstat to check the status of the cluster and the status of the network interfaces. Check the cluster log files with tail -f /tmp/hacmp.out, more /usr/sbin/cluster/history/cluster.mmdd (mmdd = current date), tail -f /var/adm/cluster.log, and more /tmp/cm.log. Check that the nodename is correct (use odmget HACMPcluster). Verify that all the HACMP Configuration is synchronized. To check the state of the HACMP cluster nodes, you have to test the topology and configuration of your HACMP cluster. This is done by using the clverify command.

rmfs (fs)

Removes the file system and will also remove the LV if there are no onther file systems on it.

defrag -q (fs) defragfs -r (fs) defragfs (fs)

Reports the fragment status of the file system. Runs in report only defrag mode (no action). Defragments a file system.

fsck (fs) Verify a file system, the file system must be unmounted! fsck (-y or -n) (fs) Pre-answer questions either yes or no ! fsck -p (fs) Will restore primary superblock from backup copy if the superblock is corrupt.

Useful HACMP commands clstat - show cluster state and substate; needs clinfo. cldump - SNMP-based tool to show cluster state cldisp - similar to cldump, perl script to show cluster state. cltopinfo - list the local view of the cluster topology. clshowsrv -a - list the local view of the cluster subsystems. clfindres (-s) - locate the resource groups and display status. clRGinfo -v - locate the resource groups and display status. clcycle - rotate some of the log files. cl_ping - a cluster ping program with more arguments. clrsh - cluster rsh program that take cluster node names as argument. clgetactivenodes - which nodes are active? get_local_nodename - what is the name of the local node? clconfig - check the HACMP ODM. clRGmove - online/offline or move resource groups. cldare - sync/fix the cluster. cllsgrp - list the resource groups. clsnapshotinfo - create a large snapshot of the hacmp configuration. cllscf - list the network configuration of an hacmp cluster. clshowres - show the resource group configuration. cllsif - show network interface information. cllsres - show short resource group information. lssrc -ls clstrmgrES - list the cluster manager state. lssrc -ls topsvcs - show heartbeat information. cllsnode - list a node centric overview of the hacmp configuration. LPAR uname –L  Use the uname command to obtain information about the system in relation to the LPAR. > uname -L -1 NULL

The "-1" indicates that the system is not running with any logical partitions, but is running in full system partition mode. The following example demonstrates how the uname command provides the partition number and the partition name as managed by the HMC: > uname -L 3 Web Server Knowing that the application is running in an LPAR can be helpful when you are assessing slight performance differences.
