Querying and sorting data
You can query the performance data in the P9000 Performance Advisor database for the last data
collection date and time stamp, for which you want to view the LDEV data. By default, your query is
executed on the latest performance data received from the selected XP or P9000 disk array. You can
also sort the LDEV data that is displayed in the LDEV table.
NOTE:
The data for the following metrics sorts in the ascending order:
• Host Group
• Chip Port ID
• ACP Pair ID
• LDEV ID
• Emulation
• Cont. Access.
The remaining metrics sorts in the descending order.
Table 18 on page 238 describes the sorting options based on which you can sort the data in the LDEV
table.
