Command Reference Guide

Administration Commands
query_local_lu
actual
The amount of kernel memory, in bytes, currently allocated to SNAplus2 components.
max_used
The maximum amount of kernel memory, in bytes, that has been allocated to SNAplus2 components at any
time since the
max_used parameter was last reset (as described for reset_max_used), or since the SNAplus2
software was started.
reset_max_used
Specifies whether SNAplus2 resets the max_used value (after returning it on this command) to match the
amount of memory currently allocated. This ensures that a subsequent
query_kernel_memory_limit
command will return the maximum amount used since this command was issued, rather than the maximum
amount used since the system was started (or since the max_used value was last reset). Possible values are:
YES
SNAplus2 resets the max_used value to match the current memory allocation.
NO
SNAplus2 does not reset the max_used value.
2.135.3 Error Return Codes
If the command cannot be executed, SNAplus2 returns a primary return code to indicate the type of error and a
secondary return code to provide specific details about the reason for unsuccessful execution.
Parameter Check
No parameter errors occur for this command.
State Check
No specific state errors, other than those listed in Appendix A, Common Return Codes from snapadmin Commands,
occur for this command.
Other Conditions
Appendix A, Common Return Codes from snapadmin Commands, lists combinations of primary and secondary
return codes that are common to all commands.
2.136 query_local_lu
The query_local_lu command returns information about local LUs. This command can be used to obtain
summary or detailed information about a specific LU or about multiple LUs, depending on the options used. It can
also obtain information about the LU associated with the CP (the default LU).
