Increase size of LUN attached to Red Hat host

Hi All,

We have a CX-700 with a LUN attached to a RHEL host. We have increased the space of the LUN via a LUN migration. What steps do we need to take to get the Linux host to see the new space?

Re: Increase size of LUN attached to Red Hat host

are you running any kind of LVM manager ? Veritas or LVM2 ?

Re: Increase size of LUN attached to Red Hat host

Googling showed this link. I have never used this method, so can't guarantee that it works. I would suggest that you take a look at using some kind of volume manager such as LVM2 for your future LUNs as using volume manager allows for much easier storage expansion.
