Naveen,  When you run symdev -sid xxx list -da all -space ==> you will see the same total capacity which you will see when you run symdisk list . Here your listing the space which is configured and unconfigured on symmetrix. If you do only symdev list --> In this you get output for all the symdevices including tdevs also and not the disks. When you do symdev list -da all --> You get output of all the raid devs and vaults but dont get tdev in them. So you need to know the difference between the comands which lists hypers and disks and need to run comand as per your need.   Regards, Mrinal Dani
I ran some commands to get the total capacity of a DMX (disregarding available or not). The first one was to find all the devices on the array and total their capacities. The other one was I had a list of all the metaheads and their sizes and they end up being greater than the size I see on the device capacity. I have been trying to find out what is wrong here and I still cannot figure it out. Thanks in advance.
Difference in total capacity
