Managing Hardware Devices
5-28 Fault Tolerant System Administration (R1004H) HP-UX version 11.00.03
Disabling a Hardware Device
The system administrator can manually take a device out of service and place it in
the ERROR state. To do this, enter
ftsmaint disable hw_path
hw_path is the hardware path of the device you want to disable.
CAUTION
Disabling a device might cause unexpected problems. Contact the CAC
before disabling a device.
The system denies a disable request if any resource in the device is critical to the
system (for example, a simplex CPU/memory board) and returns an error
message when a critical resource is involved. Otherwise, the red status light on
that device appears, and you can then safely remove it from the system.
NOTE
ftsmaint disable disables the PCI bus (not just the card) in that
card-cage and leaves it broken to avoid causing the other bay to break
when the first one is opened.
Enabling a Hardware Device
The system administrator can manually attempt to bring the device back into
service and change the state from ERROR to CLAIMED. To do this, enter
ftsmaint enable hw_path
hw_path is the hardware path of the device you want to enable.
Correcting the Error State
If a device is in the ERROR state, try to reset the device before enabling it as follows:
1. Perform a hardware reset. To do this, enter
ftsmaint reset hw_path
hw_path is the hardware path of the device.
2. Enable the device. To do this, enter
ftsmaint enable hw_path
