Step 1321-26
If you performed substep 3 of "Step 1321-24" on page 99 for the current Linux partition, go to "Step
1321-27," and when asked in "Step 1321-27," do not record any RTAS messages from "Step 1321-26" for
the current Linux partition.
Examine the Linux boot (IPL) log by logging in to the system as the root user and entering the following
command:
cat /var/log/boot.msg /var/log/dmesg 2>/dev/null | grep RTAS |more
Linux boot (IPL) error messages are logged into the boot.msg file or the dmesg file under /var/log. The
following is an example of the Linux boot error log.
RTAS daemon started
RTAS: -------- event-scan begin --------
RTAS: Location Code: U0.1-F3
RTAS: WARNING: (FULLY RECOVERED) type: SENSOR
RTAS: initiator: UNKNOWN target: UNKNOWN

RTAS: Environment and Power Warning
RTAS: EPOW Sensor Value: 0x00000001

RTAS: -------- event-scan end ----------
Step 1321-27
Record any RTAS messages found in the Linux boot (IPL) log in Step 1321-26. Ignore all other messages
in the Linux boot (IPL) log. If the system is configured with more than one logical partition with Linux
installed, repeat "Step 1321-26" and "Step 1321-27" for all logical partitions that have Linux installed.
