prestosetup - Configures the Prestoserve software
The prestosetup command is an interactive facility that allows you to set up Prestoserve on your system. Prestoserve speeds up synchronous disk writes, including NFS server access, by reducing the amount of disk I/O. The prestosetup command also allows you to modify the Prestoserve configuration on your system.
In order to use Prestoserve, your system must contain the necessary Prestoserve hardware.
The prestosetup command verifies that the Prestoserve license is registered, the Prestoserve utilities are installed, and the Prestoserve software is configured into your kernel. Note that some Prestoserve hardware configurations require different forms of kernel configuration. If the Prestoserve hardware was installed in your system when the operating system was installed, the Prestoserve software will be automatically configured into your kernel. If not, you may have to rebuild your kernel to include the correct Prestoserve controller device before you run prestosetup.
The prestosetup command configures Prestoserve on your system by asking the following questions: Do you want Prestoserve automatically enabled at system startup? Which file systems do you want to accelerate? To specify a file system, use the mount point. Do not specify a block device because some functional subsystems, such as the Advanced File System (advfs), can map more than one block device to a mount point. Do you want to start the prestoctl_svc daemon to allow remote client systems to monitor or administer a Prestoserve cache and its driver? Do you want to start Prestoserve now?
After you have entered the necessary information, the prestosetup command displays the information that you entered and prompts you to confirm that the information is correct. If the information is not correct, the prestosetup command exits and no changes are made. If the information is correct, the prestosetup command does the following: Creates the /dev/pr0 Prestoserve control device if necessary. Creates the /etc/prestotab file and includes the mount points for the file systems that you want automatically accelerated when the system starts up. Updates the /etc/rc.config file and sets the appropriate run-time configuration variables. Updates the /sbin/init.d/presto startup script with the Prestoserve configuration information from the /etc/rc.config file.
If you choose not to automatically enable Prestoserve when you start up the system, you must manually start the prestoctl_svc daemon and use the presto command to accelerate the file systems.
The prestosetup command also allows you to modify the Prestoserve configuration on your system. For example, you may want to add additional file systems to the list in the /etc/prestotab file.
Lists the mount points for the file systems that you want automatically accelerated when the system starts up.
Commands: presto(8), prestotab(4), prestoctl_svc(8)
