4.10 Understanding the Policy Advisor Analysis Process
3PAR Policy Advisor User’s Guide
4.6.1 Physical Disk Analysis
The analysis of physical disks has two functions. Failed and degraded disks in the system are
identified so that you can resolve any issues, and a summary report of physical disks in the
system is created for your information. For more information about physical disk analysis
requirements and restrictions, see Requirements and Restrictions on page 4.2. For detailed
information about the InForm OS CLI commands, see the InForm OS Command Line Interface
Reference and InForm CLI Help.
4.6.1.1 Failed and Degraded Physical Disks
You should clear or repair any faults discovered before proceeding with the tuning operations
because analysis and tuning operations do not include failed and degraded disks. This may
result in an inefficient layout and the need to re-tune the system after the disks are repaired or
replaced.
Sample output from an InServ Storage Server with failed and degraded disks is shown below:
