Red Hat 6.2 is equipped with the administration tools to setup raw devices but does not setup the raw device bindings during system start. For those environments a script named sybdevices.sh is available from $SYBASE/install/sybdevices.sh. This script contains four arguments:
show – all dedicated partitions
create – all dedicated raw device entries
bind – all dedicated raw device entries to their partitions
list – all dedicated raw device bindings
Follow below steps to administrate your system allowing Adaptive Server to initialize and gain direct access to the device mappings.
Execute $SYBASE/install/sybdevices.sh, and enter:
show
The output should be:
/dev/sdd5 88326
blocks /dev/sdd6 88326 blocks /dev/sdd7
48163 blocks /dev/sdd8 40131 blocks
From the same directory, enter:
create
The output should be:
/dev/raw/raw1 c 162 1
/dev/raw/raw2 c 162 2
/dev/raw/raw3 c 162 3
/dev/raw/raw4 c 162 4
From the same directory, enter:
bind
The output should be:
/dev/raw/raw1: bound to major 3, minor 8
/dev/raw/raw2: bound to major 3, minor 9
/dev/raw/raw3: bound to major 3, minor 10
/dev/raw/raw4: bound to major 3, minor 11
From the same directory, enter:
list
The output should be:
/dev/raw/raw1: bound to major 3, minor 8
/dev/raw/raw2: bound to major 3, minor 9
/dev/raw/raw3: bound to major 3, minor 10
/dev/raw/raw4: bound to major 3, minor 11
To guarantee that the raw device binding occurs on any system restart, open an editor on the following file:
# vi /etc/rc.d/rc.local
Add the following commands to the end of this file:
export SYBASE=`rpm -q --queryformat '%{installprefix}' sybase-common-12.5`
$SYBASE/install/sybdevices.sh bind
$SYBASE/install/sybdevices.sh list
Red Hat 7.2 is fully equipped with the administration tools to set up raw devices and administrate them during system start. To set up a Red Hat 7.2 system the partitions are administrated in the file /etc/sysconfig/rawdevices.
This is a plain text file contains comments and examples for possible configurations, as follows:
# raw device bindings# format: rawdev major minor # rawdev blockdev # example: /dev/raw/raw1 /dev/sda1 # /dev/raw/raw2 8 5
/dev/raw/raw1 /dev/sdd1 /dev/raw/raw2 /dev/sdd2 /dev/raw/raw3 /dev/sdd3 /dev/raw/raw4 /dev/sdd4
Once created, you need to bind the raw devices. This can be done by starting them from /etc/rc.d/init.d/rawdevices.
[root@legolas init.d]# cd /etc/rc.d/init.d[root@legolas init.d]# sh rawdevices startAssigning devices:/dev/raw/raw1 --> /dev/sdd5 /dev/raw/raw1: bound to major 3, minor 5/dev/raw/raw2 --> /dev/sdd6 /dev/raw/raw2: bound to major 3, minor 6/dev/raw/raw3 --> /dev/sdd7 /dev/raw/raw3: bound to major 3, minor 7/dev/raw/raw4 --> /dev/sdd8 /dev/raw/raw4: bound to major 3, minor 8
done
To guarantee that the raw device binding occurs during any restart, use the chkconfig(8) utility.
# /sbin/chkconfig rawdevices on
