The Veritas Operations Manager Enterprise Server Host Storage Assessment report shows the overall utilization percentage for each host and how hosts use storage at each level:
The Host Storage Assessment report helps you identify where most of the free storage is present.
To reclaim storage, start by assessing which hosts are good candidates for reclamation. Check the level at which the most unused storage capacity exists (LUN, volume manager, disk group, file system, or database). From the Veritas Operations Manager Enterprise Server Home page, go to Host Storage Assessment report. There, you can include or exclude virtual hosts.. You see the
Veritas Operations Manager Enterprise Server detects storage utilization for file systems and the database products that are compatible with Veritas Operations Manager Enterprise Server. Utilization percentages are calculated differently depending on what Veritas Operations Manager Enterprise Server can detect.
Table: Utilization percentage calculations for physical hosts and virtual hosts shows how utilization percentages are calculated for physical hosts and virtual hosts.

Table: Utilization percentage calculations for virtualization servers shows how utilization percentages are calculated for virtualization servers, such as ESX servers and Solaris global zones.

Use the Host Storage Utilization Grouping to target hosts with low as well as high utilization. To look for the least used hosts with the highest available capacity, check the upper-left corner of the grouping. These hosts have the highest overall capacity and are the most underused (with under 30% capacity in use).
The Distribution of Hosts bar chart shows the level at which the largest number of hosts have unused capacity. Unused capacity can be at the volume manager, LUN, or file system level. This chart also breaks down the host utilization by percentage of unused space for each level.
If a level has a large number of hosts with a lot of unused space (70-100%), examine that level in more detail. To examine the level in more detail, use the host-level reclamation reports. Go to. Then, click the link for the relevant host-level reclamation report. For example, if there is a large number of hosts with over 70% unused space at the LUN level, go to . There you see the specific LUNs that have unused space.
The Distribution of Hosts bar chart breaks capacity into unused percentage watermarks (such as 0-30%, 30-70%, and 70-100%). Select upper and lower watermarks from the Lower Water Mark and Upper Water Mark drop-down lists to filter by that watermark range.
The Hosts table provides information about all of the hosts in your environment. Table: Hosts table explains the columns in that table.
