Several parameters exist in the sysedge.cf file for preventing the SystemEDGE agent from querying the status of certain system devices, typically to avoid potential agent blocking. By default, the SystemEDGE agent does not automatically determine the status of all floppy devices on the system.
To enable floppy drive status checking, comment out the following line in the sysedge.cf file by adding a pound sign (#) character as follows:
# no_stat_floppy
You can also remove the line completely.
You can disable other device status checking that is enabled by default. To disable device status checking, enter any of the following lines in the sysedge.cf file, depending on the device that you want to restrict:
Note: Enabling any of these restrictions affects the corresponding MIB tables, because not all information will be provided for the respective objects.
Disables checking the status of all serial devices on the host system. The agent does this by default as part of its support for the hrDeviceTable of the Host Resources MIB. Some serial applications encounter problems with this operation because they cannot handle the opening and closing of serial devices (which are necessary for determining status) by any process other than themselves. When you enter this line, the agent checks only the keyboard and mouse in the hrDeviceTable and returns unknown(1) for the status of serial ports in response to a management system query.
Enables the search and find option of disk devices on SystemEDGE. If this option is disabled, the disk devices do not appear in the following SystemEDGE SNMP tables:
Note: When the no_discover_disks option is enabled, the no_probe_disks option is automatically enabled.
Disables checking the size, capacity, description, and other properties of disks and CD-ROMs installed on the underlying system to avoid potentially lengthy agent blocking on older UNIX systems while the driver waits on status information.
Note: If you add this line, the agent will discover disk devices, but may be unable to provide disk statistics, capacity information, device descriptions, and status information.
(UNIX only) Disables exposing local and remote file system data, which the agent does by default through the Systems Management Empire MIB. On some UNIX systems, checking for file system data may cause the agent to block if a file system is mounted from a remote file server that is no longer available. There is no way for the agent to unblock in this situation.
Note: If you add this line, it disables the checking of all remote file systems, not just NFS file systems.
Disables checking the status of graphics on HP-UX systems to avoid potential agent blocking.
