chnodehw
Use the chnodehw command to update the hardware configuration for a node.
Syntax
>>- chnodehw --+----------------------+--+----------+-- --------> '- -legacy -- version -' '- -force -' >--+---------------+-- ---------------------------------------->< +- object_id ---+ '- object_name -'
Parameters
- -legacy version
- (Optional) Sets the hardware configuration to make it compatible with the 6.3.0.0 code level. The format is four decimal numbers separated by periods, and there can be up to sixteen characters.
- -force
- (Optional) Allow the node to restart and change its hardware configuration
even if this will cause volumes to go offline.Important: Using the force parameter might result in a loss of access. Use it only under the direction of your product support information.
- object_id | object_name
- (Optional) Specifies the object name or ID.
Description
This command automatically reboots the node if the node hardware is different than its configured hardware. After rebooting, the node begins to use its hardware, and does not use the previous configuration.
Attention: When
you run the chnodehw command to change the configured
hardware for a node:
- Small Computer System Interface-3 (SCSI-3) reservations (through that node) are removed
- Small Computer System Interface-3 (SCSI-3) registrations (through that node) are removed
Use the -legacy parameter if you want to establish a partnership with another clustered system that is running an earlier level of code than the local system. The value supplied for the -legacy parameter must be the code level of the other clustered system.
