After sending a HUP signal to syslogd process ID as shown below, you should see your

kernel messages appearing on all consoles:

kill -1 <pid of syslogd>

Issue 3 Superuser only

Symptom You experience the following problems:

• Commands like insmod, modprobe, rmmod or rpm not available

• The RPM install fails because file permissions are being denied (see below)

Failed to open //var/lib/rpm/packages.rpm error: cannot open

//var/lib/rpm/packages.rpm

Cause Preparing a driver install necessitates access to system administrator rights

Workaround Be sure to log in as "root" before you attempt the driver install

Issue 4 The agents do not seem to expose their data through SNMP; my management console does not see any

status

Symptom Through SNMP browsers or other management software, the servers appear dead. No

SNMP traffic is available through them.

Cause This can be caused by many things. Here is a checklist of the most common problems:

• snmpd is not running

• The agents and/or drivers have not started properly

• The snmpd.conf file is misconfigured

o rwcommunity is undefined for either localhost or the management

console

o community string mismatches the one from the management console

o 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.
