Accessing Raw Devices from the Server
After you create partitions and bind the devices for raw disk I/O, Adaptive Server can use
them.
Prerequisites
Confirm that you have root privileges to execute th raw -qa command on your system, or else
you see a message such as:
Cannot open master raw device '/dev/rawctl'
(Permission denied)
Task
If Adaptive Server is running as user "sybase," then apply read, write, and owner permissions
to the /dev/raw/raw# device entries and the raw bound control device /dev/rawctl.
See the chown(1), chgrp(1), and chmod(1) commands to apply correct permissions.
1.
Verify your settings by querying the device binding with the raw command:
# raw -qa
You should see:
/dev/raw/raw1: bound to major 3, minor 5
/dev/raw/raw2: bound to major 3, minor 6
/dev/raw/raw3: bound to major 3, minor 7
/dev/raw/raw4: bound to major 3, minor 8
2.
Using the raw devices, Adaptive Server and the installation and configuration utility,
srvbuild, detect and present size automatically. Enter the absolute path to the raw device
when creating devices such as master, sybsystemprocs, sybtempdb.
