Dear managers,
I am implementing some new systems including storage within our SAN,
there are many different storage boxes (IBM, EMC) and of course, all the
systems need to be redundant, and here is where the problem comes in.
There are many methods to find out how many paths goes to one disk,
but all of these methods are not elegant, in one book I have got some
examples with the "device.info" tool but I can not find it.
I would like to find out, how many devices on one system points
to one physical disk, i. e., in Solaris I see:
/dev/dsk/c2t33d1s2 \
/dev/dsk/c3t33d1s2 --- this could be just one physical disk on the IBM-ESS
(Fiber Channel)
/dev/dsk/c4t33d1s2 /
One way to find it out, is looking into the WWN of this disk, I would love
to find the URL
where to download the "device.info" tool mentioned on the course ES 310
Yours sincerely,
Ramiro Santos
