Exporting access control information for resources to a CSV file
You can export user-related information, such as access control information, to a CSV file, which can
then be used to generate reports.
1. In the Administration tab, select User Groups.
2. From the User Groups tab or Users tab, click Export to CSV.
3. Specify the download location, then click Save.
4. Confirm that the CSV file is saved in the specified location.
Optimizing storage
This module describes how to improve your storage.
About optimizing storage
HP StorageWorks P9000 Command View Advanced Edition Suite allows you to manage storage by
allocating volumes, expanding tiers and THP/Smart pools, and performing migration, based on
information acquired from checking summaries, alerts, performance statistics, and the operating status
of storage resources. Common storage optimization issues include:
• If used capacity for a THP/Smart pool has reached a threshold, or if a volume that satisfies a ca-
pacity requirement cannot be created or assigned because the unused capacity is insufficient,
add THP/Smart pool volumes to increase the capacity of the THP/Smart pools.
• If the performance of a THP/Smart pool has decreased and data I/O is slow, add more THP/
Smart pool volumes to distribute loads within the THP/Smart pools. Another option is to perform
volume migration to distribute I/O loads on the THP/Smart pools.
• When using the Smart pool, performance problems may occur at certain times. Ensure that monit-
oring occurs during periods when I/O loads are occurring. You can:
• Start or stop the monitoring/relocation process manually in accordance with known times for
load changes.
• Cancel the monitoring process during periods of low activity.
• If Smart volume applications switch between online and batch processing, it can be helpful to
save optimized volume data placements, by processing method, as profiles. By applying the cor-
responding profile before beginning processing, the data placement that fits the characteristics of
the processing method is restored.
• When using Smart pools, you want to prioritize the data relocation of Smart volumes for which
capacity and access patterns vary widely, but I/O operations decrease without relocating effect-
ively. You can disable the relocation of Smart volumes for which the current data location presents
no problems, to reduce relocation load.
• When using Smart pools, important data is allocated to the lower hardware tier because it has
fewer I/O accesses. To prevent unwanted relocations, set a specific hardware tier for the Smart
by configuring the tiering policy.
• If the load on a volume is too high when volume data is backed up to tape, create a copy pair
for the volume. Then do a tape backup by using the copied volume (as a secondary volume).
• If it's not possible to assign a high-performance volume to a host because all unassigned volumes
are low performance, perform volume migration so that less frequently used data is migrated to
a low-performance volume, and then assign the now available high-performance volume to an
appropriate host.
