Hi Bill,
Although i am using this forum a lot, this is my first time to join...
Everytime we create FS and LVs, we need to check first the free space of our VGs right? That's why i created this script. This give me an idea how much is the free space on each VGs. Hope this help :)
BTW, could anyone send me a script that will help me simplify my jobs in Symmetrix & BCV? Appreciate so much if you guys can send it over. Thank you so much!
