Hanged HP-UX and Running HP-UX Detection

This section describes how you can determine whether HP-UX still is

running on an nPartition even when you are unable to login or access the

nPartition console.

You also may wish to reference the information in the procedure

Conﬁguring Automatic System Restart for a nPartition on page 236 for

details on conﬁguring an nPartition to reboot when HP-UX has hanged

on it for over three minutes.

Detecting if HP-UX is Running or Hanged on an nPartition

To determine whether HP-UX is running or has hanged on an nPartition

use this procedure (ﬁrst check the Virtual Front Panel, then check the

Chassis Logs menu’s Live Logs display, then the nPartition’s Console).

Refer to the chapter Using Console and Service Processor Interfaces on

page 125 for details on service processor login accounts and features.

Step 1. Access and view the nPartition’s Virtual Front Panel (VFP).

nPartition resides, enter VFP to access the VFP menu, and select the

nPartition whose boot state you want to check.

• To exit an nPartition’s VFP, type ^b (Control-b).

• When HP-UX has booted on the nPartition, HPUX heartbeat is

displayed as the partition state when you view the nPartition VFP.

• If HP-UX is alive, an asterisk (*) blinks on and off in the partition

state area of the nPartition VFP.

Also see Boot States and Activities for nPartitions and Cells on page 194

for details interpreting the VFP status.

Step 2. If the nPartition VFP indicates that HP-UX has booted but is not alive,

exit the VFP and view the live chassis logs for the nPartition.

At the GSP main menu, enter SL to enter the Show chassis Logs menu,

and enter L to select the Live Chassis Logs display from the Chassis Logs

menu.
