Notes on performing monitoring
• You can collect the monitoring data even while performing the relocation.
• After stopping the monitoring, the tier range is automatically calculated.
• The latest available monitoring information, which is collected just before the relocation is
performed, is used for the relocation processing.
• When the relocation is performed, the status of the monitor information must be valid.
Viewing monitor and tier relocation information:
If the raidcom get thp_pool command is executed with the -key opt option specified, the
monitoring information and tier relocation information are displayed. For details about the raidcom
get thp_pool command, see HP XP7 RAID Manager Reference Guide. Items are displayed as
follows:
