Configuring Storage for Oracle Clusterware Files on Raw Devices
Table 4–4 (Cont.) Raw Disk Devices Required for Database Files on HP-UX
Number Size (MB) Purpose and Sample Alternative Device File Name
2 110 First and second control files:
dbname_control{1|2}_raw_110m
1 5 Server parameter file (SPFILE):
To configure shared raw disk devices for Oracle Clusterware files, database files, or
both:
1. If you intend to use raw disk devices for database file storage, then choose a name
for the database that you want to create.
The name that you choose must start with a letter and have no more than four
characters, for example, orcl.
2. Identify or configure the required disk devices.
The disk devices must be shared on all of the cluster nodes.
3. To ensure that the disks are available, enter the following command on every
node:
# /usr/sbin/ioscan -fun -C disk
dbname_spfile_raw_5m
1 5 Password file:
dbname_pwdfile_raw_5m
The output from this command is similar to the following:
Class I H/W Path Driver S/W State H/W Type Description
==========================================================================
disk 0 0/0/1/0.6.0 sdisk CLAIMED DEVICE HP DVD-ROM 6x/32x
/dev/dsk/c0t6d0 /dev/rdsk/c0t6d0
disk 1 0/0/1/1.2.0 sdisk CLAIMED DEVICE SEAGATE ST39103LC
/dev/dsk/c1t2d0 /dev/rdsk/c1t2d0
This command displays information about each disk attached to the system,
including the character raw device name (/dev/rdsk/cxtydz).
Note: On HP-UX 11i v.3, you can also use agile view to review mass
storage devices, including character raw devices
(/dev/rdisk/diskxyz). For example:
#>ioscan -funN -C disk
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
disk 4 64000/0xfa00/0x1 esdisk CLAIMED DEVICE

disk 907 64000/0xfa00/0x2f esdisk CLAIMED DEVICE
COMPAQ MSA1000 VOLUME
/dev/disk/disk907 /dev/rdisk/disk907
4. If the ioscan command does not display device name information for a device
that you want to use, then enter the following command to install the special
device files for any new devices:
