Reboot Corrupts the Kernel Registry

(Itanium Systems Only)

The reboot command used with the -r -n -q options corrupts

the kernel registry /stand/current/krs/config.krs after

reboot. You may encounter this defect when using the Oracle 10g

RAC with the cluster ready service. Any error detected by Oracle

leading to the reboot -n may cause this corruption and result

in an unusable system. If you do encounter this problem you will

be presented with messages similar to the following:

/sbin/ioinitrc: /sbin/krs_sysinit: ERROR: Unable to retrieve

module information from configuration 'current':

kc_kr_open_node(/kconfig/Modules): KRS error code 2

WARNING: Unable to load modules scheduled to be loaded at boot

time: kc_mod_get failed.

ERROR: Unable to read title of running configuration: KRS error

code 2

WARNING: Unable to read the currently booted kernel configuration

in order to generate an updated system file. The system file may

be out of sync with the booted kernel configuration.

What To Do

HP recommends that customers boot from a stable backup.
