Hi,
check errpt if you were maybe running out of pagingspace of if you exceeded the maximum allowed pinned pages.
If you are running a cluster, it may be the cluster software or application that caused the reboot - Oracle rac tends to occasionally boot a node or both in case of various problems like lost heartbeat or major application issues - hacmp does similar things.
Another possibility is that you are facing problems on the hardware (like memory or cpu errors on the frame itself) which may cause the frame to reboot your lpar to free up the faulty resources.
Kind regards

crm_uuid
CRM_UUID(8) [FIXME: manual] CRM_UUID(8)
NAME
crm_uuid - get a node's UUID
SYNOPSIS
crm_uuid [-w|-r]
DESCRIPTION
UUIDs are used to identify cluster nodes to ensure that they can always be uniquely identified. The crm_uuid command displays and modifies
the UUID of the node on which it is run.
When Heartbeat is first started on a node, it creates a UUID (in binary form) in /var/lib/heartbeat/hb_uuid. This file can be read and
written by means of crm_uuid.
Note
There are very rare circumstances when crm_uuid should be used to modify the UUID file. The most common is when it is necessary to set
a node's UUID to a known value when creating a new cluster.
OPTIONS
--write, -w
Write a UUID value to the /var/lib/heartbeat/hb_uuid file.
Warning
Use the -w option with care, because it creates a new UUID value for the node on which it is run. Various scripts across the
cluster might still use the old value, causing the cluster to fail because the node is no longer associated with the old UUID
value. Do not change the UUID unless you changed all references to it as well.
--read, -r
Read the UUID value and print it to stdout.
SEE ALSO
/var/lib/heartbeat/hb_uuid
