https://community.hpe.com/t5/operating-system-hp-ux/pvmove-question/m-p/3351762#M625601 Hello,<BR /><BR />I have a volume group that has one logical volume and it spans 6 LUN's. I want to replace one LUN in this 6 with another one. It is not striped.<BR /><BR />Can I use this {pvmove /dev/dsk/c1t0d0 /dev/dsk/c2t0d0} like in the man page?<BR />I am not sure as the man page is 100% clear when there is a LV that spans more than one LUN.<BR /><BR />Any help appreciated.

Also make sure you dont interrupt the command in between :-)<BR /><BR />If you can take a downtime of the system, install the latest LVM cumulative patch before going ahead with the change</NEW-LUN></NEW-LUN></NEW-LUN> Fri, 06 Aug 2004 18:16:21 GMT https://community.hpe.com/t5/operating-system-hp-ux/pvmove-question/m-p/3351763#M625602 Sundar_7 2004-08-06T18:16:21Z
