Using The Set_Fixed Utility To Restore Hardware Up State - HP B6191-90029 User Manual

Using the set_fixed Utility to Restore Hardware UP State
Most hardware event monitors cannot detect when a hardware failure has been repaired and the resource has
been returned to normal operation. Consequently, these monitors cannot alert the PSM to change the status
of its hardware resources from DOWN to UP. It is necessary for you to manually change the status of the
hardware resources using the set_fixed utility included with the PSM. To determine if a monitor requires
use of the set_fixed utility, refer to the monitor descriptions in Chapter 6, "Monitor Data Sheets."
The set_fixed utility includes its own man page describing how to change the state of the resource.
NOTE Make sure you have repaired the problem before you use the set_fixed utility to return the
hardware resource status to UP. If the hardware is not repaired, the change in status to UP
may cause MC/ServiceGuard to erroneously assume the hardware is working properly.
To restore the operating state of a resource to UP:
1. If necessary, list the hardware resources that currently have a status of DOWN by typing:
/etc/opt/resmon/lbin/set_fixed -L
2. Set the status of the DOWN hardware resource to UP by typing:
set_fixed -n resource_name
The resource_name is the status resource path name to the hardware resource that has been repaired. When
specifying the resource_name you can use wildcards such as "*" to indicate all instances.
Example 4-1 Example of Using set_fixed
The following example sets to UP the status of the SCSI tape device at hardware path 10_12_5.0.0
set_fixed -n /storage/status/tapes/SCSI_tape/10_12_5.0.0
The following example sets to UP the status of all AutoRAID disk arrays.
set_fixed -n /storage/status/disk_arrays/AutoRAID/*
