Hi,


Put option 7,8 after option 12 on first page.i.e. do a vgexport after extending the lvol & file system. Rest is fine.

Hi,

You cannot export when the VG is active, Hence steps 7 and 8 should be followed after step 13.

FOR EXTENDING I CORRECT YOU WORKING PLANS AS FOLLOWING;

Extend a VG in cluster (two new disk), and extend LV and FS

nodo e ( active):

1.- # ioscan â fnC disk ï ¨ to see the new disks

2.- # cmhaltpkg -v â paqueteâ ï ¨ halt the package

3.- # vgchange -a e /dev/vgXX ï ¨ to activate VG

4.- # pvcreate /dev/rdsk/cXtYdZ .

5.- # vgextend /dev/vgXX /dev/dsk/cXtYdZ /dev/dsk/cRtVdW

6.- # vgdisplay vgXX ï ¨ to verify the new size

7.-------

8.- # lvextend -L "nuevo tamaño en Mb" /dev/vgXX/lvolXX ï ¨ extend the LV

9.- # extendfs /dev/vgXX/lvolXX ï ¨ extend the filesystem

EXPORT VG MAP SHOULD DO AFTER EXTENDING LV

# vgexport -v -p -s -m /tmp/vgXX.map /dev/vgXX ï ¨export the VG.

I RECOMMEND YOU COPY CONFIG FIL AT THIS STEP (AFTER EXTENDING)
10.- Copy the mapfile to node B

11.- # mount /dev/vgXX/lvolXX /tmp_test ï ¨ to verify the new size

12.- # umount /tmp_test

13.- # vgchange -a n /dev/vgXX ï ¨ to deactivate the VG in the node A

14.- # vgimport â v â s â m /tmp/vgXX.map /dev/vgXX ï ¨ import the VG in node B

15.- # cmrunpkg -n "node" â packageâ ï ¨ Stara the package in the node.

Thanks to all, the procedure was well, i had to do any change for example export VG without options to erase it of lvmtab file and after to make the import.
