The value of the Equipment Type field of the Master Configuration File (mcf) identifies devices and device configurations within the SAM-QFS software using two-character codes. This glossary lists the codes for quick reference when working with the samples or when interpreting an existing mcf (for full details see the mcf(4) man page).
For convenience, the codes are divided into three sections and then listed alphabetically:
This section describes all of the equipment codes that you normally need: the generic equipment codes (rb, tp, and od) and codes for identifying network-attached library interfaces and the SAM-QFS historian.
The generic equipment codes rb, tp, and od are the preferred equipment type codes for all SCSI-attached libraries, tape drives, and optical disk devices. When you specify a generic equipment type, SAM-QFS can automatically set the correct type based on SCSI vendor codes.
Where XXX is an integer in the range [0-127], a striped group of disk devices that is part of an ma disk-cache family set.
The SAM-QFS historian, an optional, virtual library that maintains a media catalog, but has no associated hardware. Used for tracking exported media.
A high-performance QFS file system that maintains file-system metadata on one or more dedicated mm disk devices. File data resides on separate md, mr, or gXXX data devices.
A disk device that stores file data for an ma file system or data and metadata for an ms file system. md devices store file data in small, 4-kilobyte Disk Allocation Units (DAUs) and large, 16-, 32-, or 64-kilobyte DAUs. The default DAU is 64-kilobytes.
A disk device that stores file-system metadata for a high-performance ma file system.
A disk device that stores file data for an ma file system. mr devices store file data in large, fully adjustable Disk Allocation Units (DAUs) that are multiples of 8 kilobytes in the range 8-65528 kilobytes. The default DAU is 64 kilobytes.
A SAM-QFS file system that maintains file-system metadata on the same devices that store file data.
Any SCSI-attached optical disk. SAM-QFS sets the appropriate equipment type automatically using the SCSI vendor code.
Any SCSI-attached tape library. SAM-QFS sets the appropriate equipment type automatically using the SCSI vendor code.
The SAM-Remote pseudo-device. In the Master Configuration File (mcf), the corresponding Equipment Identifier field has to contain the path to the pseudo-device (such as /dev/samrd/rd2). The corresponding Family Set field has to contain the hostname of the SAM-Remote server.
A SAM-Remote client system. In the Master Configuration File (mcf), the corresponding Equipment Identifier field has to contain the path the SAM-Remote client-configuration file for the client. The corresponding Family Set field has to contain the family set name of the server. The Additional Parameters field must contain the full path to the client's library catalog file.
An Oracle StorageTek ACSLS interface to a network-attached library. In the Master Configuration File (mcf), the corresponding Equipment Identifier field has to contain the path to the parameters file for the ACSLS interface. For more information, see the stk(7) man page.
A SAM-Remote server. In the Master Configuration File (mcf), the corresponding Equipment Identifier field has to contain the path to the SAM-Remote server-configuration file. The corresponding Family Set field has to contain the family set name of the server, which must match the name used in the Family Set field of the mcf on the client.
Any SCSI-attached tape drive. SAM-QFS sets the appropriate equipment type automatically using the SCSI vendor code.
The equipment types listed in this section are also supported.
Note that, in most cases, Oracle recommends identifying SCSI-attached libraries, tape drives, and optical disk devices using the generic equipment types rb, tp, and od. The generic equipment types tell SAM-QFS to identify the hardware dynamically, using SCSI vendor IDs. The type codes below are essential when migrating from one media type to another and may sometimes be useful for management purposes. But using them in a Master Configuration File (mcf), for example, hard-codes a static equipment configuration that may not match the actual hardware.
