I faced the same issue,
what i did is I made a script in for Loop that selects each host and run the syntax for each host.
at the end the script returns me total value of each host.
you can try this.
i have one quick question too
what is the unit of the capacity that is shown in the output. as i see total sum of all the capacity that i get from CLI doesn't match anywhere near my exact storage capacity.
please let me know on this.
i have the solution for DMX and VMAX.
For DMX you have to use SymmReport tool. Through that tool a xls file will be generated for all hosts. A big amount of info will be found in that xls!!!!
For VMAX you can use the SMC to find the total allocated capacity for all Storage Groups.
If you Unisphere for VMAX, EVEN BETTER!!!!!!!!
As Dynamox told me that SymmReport is not available to the customer, then for DMX if you have created aliases you could use the "symmaskdb -sid XXXX list capacity -Host hostname" command.
Also via Prosphere as Dynamox said.
How do I get to try this script? Is the script available still on the link you've provided above? I tried but no luck. Kindly help me out here.
