 in Ver is the Cause

After initiating the following workaround, Addition of Redo Logfiles to RAW 
Devices was successful.


P.S. Workaround is Rename the /usr/sbin/lvmchk binary:-

   cd /usr/sbin
   mv lvmchk

Qs Should the "b" (block device) file - /dev/vg02/rawdb1 OR the "c" (character 
device) file - /dev/vg02/rrawdb1 be used?
Have used BOTH names without success.

NOTE - This is a NON-ASM, NON-RAC Oracle Setup with Database on Mounted 

An Old Oracle ver 8 metalink Doc 1051188.6 indicates that Oracle uses only "c" 
- character device files as raw devices.

HP-UX B.11.23


P.S. Errors:-

SQL> alter database add logfile group 3 ('/dev/vg02/rrawdb1') size 500M ;
