The HACMP clstat command does not work

Clinfo daemon started?


The clstat command retrieves the information from the clinfo daemon. This daemon is not started automatically. It is an option in the SMIT HACMP startup menu (smitty clstart). If it is not running, stop HACMP on this node, and start it up again with clinfo activated.

To check the status of the HACMP processes: lssrc -a | grep -E "ES | svcs"

SNMP version in AIX 5L version 5.2


AIX 5L version 5.2 uses SNMP version 3 agents, whereas HACMP uses a SNMP version 1 configuration. Both clinfo and CSPOC require SNMP version 1. With the default SNMP agent, the clinfo daemon is not able to supply cluster information, thus the clinfo command will not work properly.

Run the script provided in Example 3-38 to switch to version 1 agents.

Example 3-38 Switch SNMP agents to version 1

#!/bin/kshLOG=/var/adm/chg_snmpd.logtouch $LOG/usr/es/sbin/cluster/utilities/clstop -N -g >> $LOG 2>&1sleep 5for i in muxatmd aixmibd snmpmibd hostmibd snmpddostopsrc -s $i >> $LOG 2>&1sleep 2doneln -sf /usr/sbin/snmpdv1 /usr/sbin/snmpdfor i in snmpd hostmibd snmpmibd aixmibd muxatmddostartsrc -s $i >> $LOG 2>&1sleep 2donesleep 10/usr/es/sbin/cluster/etc/rc.cluster -N -i >> $LOG 2>&1sleep 5

You can also use the following command to change the running SNMP configuration back to version 1:

/usr/sbin/snmpv3_ssw -1

For security reasons do not use the default "public" SNMP community. You can change the community name in the /etc/snmpd.conf file, then stop cluster services (incl. clinfo) and specify this new name to clinfo: chssys -s clinfo(ES) -a "-c NEW_COMMUNITY_NAME" , then restart HACMP.

VIM Faster Navigation

Sometimes even the simplest of tasks like navigating through a single file can be optimized. Vim offers several methods of navigation within a file, which can adapt to the contents of the file and how it is organized. Some of these methods are obvious, while others are more complex. Mostly, the files we are editing are well structured. If our files are text, then this structure can be in the form of paragraphs, sentences, and words, or at other times code with functions, blocks, and code lines. Vim supports jumping around the file, according to the structure in the file, and has key bindings that make it easy to go to the exact place in the file where you want to go. Moving within a text file You are working on a normal text file and in the middle of a sentence you realize that you have forgotten to make the first letter in the paragraphs uppercase. You could of course, use the arrow-keys or the h/j/k/l navigation keys to move to the beginning of the paragraph to cor...

ESS Subsystem Device Driver setup

In a high availability environment, there is a special device driver, designed for ESS, named Subsystem Device Driver (SDD). This device driver allows for redundant links and load sharing for storage traffic when multiple fiber connections exist between nodes and the ESS storage subsystem. SDD comes as an AIX installable fileset, named ibm2105.rte. This has to be installed on all cluster nodes, even if not all nodes in the cluster have more than one FC adapter. In our configuration, since each node is connected to the ESS using two optical cables, each disk can be accessed via any of the two paths. When SDD is installed, a virtual path is created. This virtual path represents the same storage space, but is accessible via both fiber links. There are two versions of the SDD driver for AIX: ibmSdd_510.rte - This is suitable for non-HACMP configurations or for concurrent HACMP (HACMP/ESCRM). ibmSdd_510nchamp.rte - This has to be used in nonconcurrent HACMP environments. In our...
