ECO KIT SUMMARY:
A dupatch-based, Early Release Patch kit exists for HP TruCluster Server V5.1B-3
that contains solutions to the following problem(s):
Code introduced in Tru64 UNIX V5.1B-3 may cause a CPU hang due to a hung
"drd_event_thread" in "drd_reopen_partitions".
The drd_thread sometimes gets into infinte loop when any one of several DRD
blocking flags is set. This happens when the disk is in I/O DRAINED state.
