To Re-Enable Dump Detection; Swap Space; Reconfiguration After A Dr Operation - Sun Microsystems Sun Enterprise 10000 Dynamic Reconfiguration User Manual

To Re-Enable Dump Detection

1. Log in to the SSP as the user ssp.
2. Disable record-stop dump detection:
SSP% edd_cmd -x stop
This command suspends all event detection on all of the domains.
3. Monitor the in-progress record-stop dump:
SSP% ps -ef | grep hpost
In the grep(1) output, the -D option of hpost indicates that a record-stop dump is
in progress.
4. Perform the DR Detach operation.
5. Enable event detection:
SSP% edd_cmd -x start

Swap Space

The domain swap configuration consists of the swap devices and swapfs (memory).
The domain must contain enough swap space so that it can flush pageable memory.
For example, if you want to remove 1 Gbyte of memory from a 2-Gbyte domain, you
will need 1 Gbyte of swap space, depending on the load. Insufficient swap space
prevents DR from completing the detach of a board that contains memory. If this
happens, the memory drain phase does not complete, so you must abort the detach
operation.

Reconfiguration After a DR Operation

This section describes how to reconfigure your domain after you have attached or
detached a system board.
