How to Find ASM Disk to Physical Device Mapping

1. List Oracle ASM Disks

# /etc/init.d/oracleasm listdisks
DV242ASM00
DV242ASM01
DV242ASM02
EMCPPA1
EMCPPB1

2. Query Disk

# /etc/init.d/oracleasm querydisk -d EMCPPB1
Disk “EMCPPB1” is a valid ASM disk on device [8, 33]

3. Match Major/Minor Numbers to Physical Disk

# ls -l /dev | grep 8|grep 33
brw-rw—- 1 root disk 8, 33 Jul 25 17:38 sdc1

How to Clear Faults Using the Oracle ILOM Command-Line Interface

Log in to the Oracle ILOM CLI.
Use the following command to clear the fault for a specific component.
–>set pathtocomponent clear_fault_action=true

where pathtocomponent is the path to the component for which you want to clear the fault.

For example:

set /SYS/BL0/P0/D0 clear_fault_action=true

Issue:
RMAN-10035: exception raised in RPC: ORA-19504: failed to create file “/u94/oradata/msctest/bomd02.dbf”
ORA-27044: unable to write the header block of file
HP-UX Error: 27: File too large

or

ORA-01237: cannot extend datafile 222
ORA-01110: data file 222: ‘/u95/oradata/mscprod/invdl412.dbf’
ORA-27059: skgfrsz: could not reduce file size
HP-UX Error: 27: File too large
Additional information: 1

Check if large files are supported:
# fsadm -F vxfs /u94
nolargefiles

Fix:
# fsadm -F vxfs -o largefiles /dev/vg05/u94

# fsadm -F vxfs /u94
largefiles

Add largefiles option to the list of vxfs options in /etc/fstab:
dev/vg08/u94 /u94 vxfs delaylog,largefiles 0 2

You may need to remount the filesystem if is not an Online JFS or VxFS.
