Enabling asynchronous disk I/O

To enable asynchronous I/O, install the HP asynchronous I/O driver from the SAM Kernel Configuration menu:

1. Close Replication Server.

2. Click Kernel Configuration.

3. Click Drivers.

4. Set the Pending State for asyncdisk to In.

5. From the Actions menu, rebuild the kernel, and restart the system.

6. At the UNIX command prompt, run the following statements as “root”.

   /etc/mknod /dev/async c 101 4
   chmod 0660 /dev/async
   chown sybase /dev/async
   

The user who starts Replication Server must be the owner of the /dev/async directory, or must have write permission on the directory.

Contact your operating system administrator or HP technical support for help with installing this driver.
