https://community.hpe.com/t5/operating-system-hp-ux/extend-disk/m-p/3488135#M214447 Hi,<BR /><BR />Is it possible to extend a physical (SAN) volume without destroying the data on the disk ? As far as I know, it is not possible with LVM, is there any difference with VxVM.<BR />(HP-UX 11.23, VxVM 3.5 ) Thu, 17 Feb 2005 12:12:59 GMT Leif Halvarsson_2 2005-02-17T12:12:59Z https://community.hpe.com/t5/operating-system-hp-ux/extend-disk/m-p/3488135#M214447 Hi,<BR /><BR />Is it possible to extend a physical (SAN) volume without destroying the data on the disk ?

Sadly, I'm 7000 miles away from my machines and not certain the process is documented anyway.<BR /><BR />I think the success on LVM depends on who built the SAN. It might be possible with an HP built/marketed disk array. It might be possible with one of the expensive Veritas add on products.<BR /><BR />I have not tried it with your OS combo, or VxVM.<BR /><BR />SEP Thu, 17 Feb 2005 12:19:37 GMT https://community.hpe.com/t5/operating-system-hp-ux/extend-disk/m-p/3488136#M214448 Steven E.
