NAME

spinup, spindown − spin up/down Remote Virtual Disk (RVD) pack

SYNOPSIS

spinup [ −f ] drive server name mode [ password ]
spindown −a
spindown drive

DESCRIPTION

Spinup spins up an RVD pack.  The −f flag forces prompting for the command authorization password.  Drive is a single digit integer denoting the drive number on which to spin up the virtual pack.  Server is the name of the host serving the pack.  Name is the name of the remote disk pack.  Mode is the mode in which to spin up the virtual pack.  Modes may be one of only ‘r’ or ‘x’ for either read-only or exclusive mode.  Password is the password for the specific spinup mode.  Password is unnecessary if the local host “owns” the remote pack.  If the pack is not owned by the local host and the password is not supplied on the command line, spinup prompts for the password. 

Spinup changes ownership of the devices associated with drive to that of the invoking user (see getuid(2)).

Spindown spins down an RVD pack.  The −a flag spins down all drives.  Drive is a single digit integer denoting the drive number to spin down. 

Spindown restores the ownership of the devices associated with drive to root.

Warning: The virtual file system must be unmounted when the virtual disk is spun down, or the system may hang or crash (see umount(1)).
