Preparing a driver install necessitates access to system administrator rightsCause
Be sure to log in as "root" before you attempt the driver installWorkaround
The agents do not seem to expose their data through SNMP; my management console does not see
any status
Issue 4
Through SNMP browsers or other management software, the servers appear
dead. No SNMP traffic is available through them.
Symptom
This can be caused by many things. Here is a checklist of the most common
problems:
Cause
• snmpd is not running
• The agents and/or drivers have not started properly
• The snmpd.conf file is misconfigured
◦ rwcommunity is undefined for either localhost or the management console
◦ community string mismatches the one from the management console
◦ trapsink or trapcommunity is undefined; trapcommunity may be undefined
for localhost
• Firewalling software is enabled on the system and set up to block SNMP
traffic
• The cmaX extension is absent from the SNMP stack
Workaround
• Restart snmpd if it is not running
• Start hp-health and hp-snmp-agents typing “/etc/init.d/
hp-health restart” and “/etc/init.d/hp-snmp-agents
restart”
• Configure snmpd.conf file appropriately for your environment. See “man
snmpd.conf” for more information
• Ensure SNMP traffic is allowed through firewall
• Ensure cmaX extension is included in the SNMP stack. See “man
hp-snmp-agents” for more information.
Table 17 (page 33) describes common problems that might occur during installation and operation
of the Host OS Agent, the Standard Equipment Agent, the SCSI Agent, the System Health Agent,
the Threshold Agent, and the Peer Agents. In most cases, a workaround is available.
