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. SEE ALSO inquiry.conf(4), mcf(4). historian(7), samst(7). st(7D).
