mccfg - Media Changer Configuration
The mccfg command is a two-part Sun Storage Archive Manager
(SAM-QFS) media changer and tape drive installation
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.
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
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
mcf The configuration file for SAM-QFS environments.
Run samd config for mccfg changes to take effect.
