hrDevice Group Maintenance

Values in the hrDevice group support the following device types:
Processors
Network
interfaces
Printers
Disks
Tape
devices
OSS filesets
Some of these devices are also represented in the hrPartitionTable and the hrFSTable.
The subagent assigns one partition and one file system per logical disk, using the
information it maintains for writable disks.
One entry appears in the hrDeviceTable for each of the six preceding device types
listed above. Indexes for each entry, derived from a range of values unique to each
device type as described in
hrProcessorTable, hrNetworkTable, hrPrinterTable, hrDiskStorageTable, and
hrPartitionTable. Once assigned, a device index is never reused, even when a device
is removed from the system. When a new device is added to the system, it is assigned
an index value that has never been used from the assigned range of index values.
The subagent uses Guardian procedures PROCESSORSTATUS,
PROCESSORTYPE, and PROCESSOR_GETINFOLIST_ to
construct processor entries in the hrProcessorTable.
The subagent accesses the network interface file to build
hrNetworkTable entries. Refer to
on page 11-12 for a description of how the -f startup parameter is
used to identify the network interface file.
The subagent uses Spooler procedure SPOOLERSTATUS2 and
Guardian procedure FILE_GETINFOLISTBYNAME_ to obtain
information about printers for the hrPrinterTable. The Spooler can
define virtual printers, usually collector processes that forward print
jobs to a remote printer. Entries are also created for virtual printers.
The subagent uses Guardian procedures
DEVICE_GETINFOBYLDEV_ and FILE_GETINFOLISTBYNAME_ to
construct entries in the hrDiskStorageTable for both read-only disks
and other disks.
The subagent creates entries describing tape devices by using
Guardian procedure DEVICE_GETINFOBYLDEV_.
The subagent creates entries for OSS filesets by reading the
ZXCONFIG file.
