need to confirm:
we have a system with two VIOs each serving a partition on a local disk to a client LPAR. That client LPAR has them both in a VG which is mirrored (exact). So each disk has a copy of the client LV that the client VG supports. This is the setup that was bequeathed to us by the... (3 Replies)

class_init
class_init(3) Library Functions Manual class_init(3)
NAME
class_init - Initialize the class scheduler database
LIBRARY
Standard C Library (libclass.a)
SYNOPSIS
#include <sys/class.h>
class_init(void)
DESCRIPTION
Prepare the class scheduler database for use by: opening the disk file (if any) creating (or attaching to) a shared memory section creating
(or attaching to) a semaphore
Before class scheduling can be used, the database must be initialized. At the first call of class_init() since the last boot, the function
creates a shared memory segment for the database and, if it exists on disk, reads it into the shared memory. A semaphore is also created
that is used to synchronize potential simultaneous database updates (for example, from class_admin(8) or runclass(1)).
On subsequent calls to class_init(), the function attaches to the existing shared memory and semaphore.
Note that the calling process must have root access privileges
RETURN VALUES
Operation successfully completed. Not super user - permission denied. Failed to access disk file, if it exists. Failed to create or
attach to shared memory. Failed to create or attach to semaphore.
