Allocation queries

A noob question , need your help please .

In our environment requests are like , "Add 1 TB to F drive" | "Expand D drive by 2 TB " .

From the Clariion or Vmax that we manage I can only see Luns , how can I identify

what lun is mapped where

which one to expand

Is there anyway I can check which is the target Lun I should be expanding as (D/E/F drive ) dosen't make any sense to me cos i dont know .

Peace !

If its a one to one relationship then I shoud be expanding the same tdev .

Its always good to check the how the devs are mapped at the host end . I shouldn't be expanding any devs blindly

is what I get .

Can multiple devs(meta) be mapped to a single drive letter ? Let say I have two metaheads 0EFC&0EFE , can they be merged into a single drive .

Want to understand how it works in unix/windows .. I've read about primary/extened /dynamic disks ..

you can merge them by converting both devices to dynamic drives and then spanning. I have always hated using dynamic drives on Windows, try to avoid it as the plague.

On *nix platforms don't expand devices, you have very nice logical volume managers so you typically add another device to the operating system and expand the LVM (volume group, logical volume and then the file system)
