we will migrate our cor systems SAP from Solaris which running on Sparc servers to red hat 7.x red hat enterprise which will run on vmware
i don't really know if this good or bad but the manager deiced like this and we are going to do it .
but the question is
we use to use veritas volume manger VXVM to manage or volumes on Solaris
and my manger said after we move to red hat we will not use VXVM because of the license
so my question what the best replacement for VXVM in our case to have full flexibility to expand and shrink and mirror - replicate - etc the volumes on red hat
i don't know about LVM and i don't know how we can manage this
any idea ? any advice ? it will be appropriated .
