mccfg(1M) - Sun QFS and Sun Storage Archive Manager 5.3 Reference Manual

NAME
     mccfg - Media Changer Configuration

SYNOPSIS
     /opt/SUNWsamfs/tools/mccfg

AVAILABILITY
     SUNWsamfs

DESCRIPTION
     The mccfg command is a two-part Sun Storage Archive Manager
     (SAM-QFS) media changer and tape drive installation
     configuration script.

     The first part configures /kernel/drv/samst.conf lun 0 fc-
     fabric media changers.

     The second part configures /etc/opt/SUNWsamfs/mcf for both
     parallel and fc-fabric SCSI media changers, media changer
     installed tape drives, and standalone tape drives.  Media
     changer installed tape drives are put in the required
     /etc/opt/SUNWsamfs/mcf ascending order for proper
      SAM-QFS operation. A historian is also be added to the
     /etc/opt/SUNWsamfs/mcf.  Missing device information in
     either /etc/opt/SUNWsamfs/inquiry.conf or
     /kernel/drv/st.conf produces a warning.

     Multipath devices are supported where the first path seen is
     used in the /etc/opt/SUNWsamfs/mcf configuration.

LIMITATIONS
     Network-attached media changer installed tape drives are
     configured as standalone tape drives.  The user must create
     the /etc/opt/SUNWsamfs/mcf virtual library entry and change
     the standalone tape drive's family set to that of the
     virtual library's.

     Parallel SCSI-2 media changer and installed tape drives need
     to be on the same SCSI bus for automatic configuration.
     However, a single bus is not a requirement of SAM-QFS, and
     better performance is achieved with multiple buses.

     A media changer which is lun 1 fc-fabric WWN must be
     manually /kernel/drv/samst.conf configured because of cfgadm
     and luxadm limitations.

     For automatic configuration to work, all removable media
     equipment must be able to be opened and respond to a USCSI
     commands.

FILES
     mcf       The configuration file for SAM-QFS environments.

NOTES
     Run samd config for mccfg changes to take effect.
