Hi,
Below is a listing of "multipath -ll" which are the same across
both our RAC servers (as the bindings file are identical).
Currently our NetApp Filer1's load is very heavy while Filer2
is underutilized
Question 1:
a) how do we find out which of the device files /dev/sd*
a) how do we find out which of the device files /dev/sd*
go to NetApp SAN Filer1 & which to Filer2 (we have 2
NetApp files)?
b)on the lines below with "round robin", what does "enabled"
& "active" mean or what's the difference? Does "active"
b)on the lines below with "round robin", what does "enabled"
& "active" mean or what's the difference? Does "active"
refers to the primary path it goes to & when the primary
filer fails, then only secondary filer took over?
