I understand that with HP 11.11 Online jfs is free , but it does not work for , do i have to enable something .

With 11.11, OnLineJFS is not free in the base (foundation) Operating Environment. It is bundled in the higher cost Enterprise Operating Environment and the Mission Critical Operating Environment.

Hello Manu,
If the file system you want to extend is full (100%) On-Line JFS could not work, try reduce it a little bit and extend it.

I may be wrong here, but I didn't think SAM can use OnlineJFS.

Try from command line:

lvextend -L /dev/vgXX/lvolXX
fsadm -b M /mountpoint

Example:

lvextend -L 768 /dev/vg10/lvmirrlogA
fsadm -b 768M /oracle/BWP/mirrlogA

Sam can use OnlineJFS. Your first task should be to see if OnlineJFS is actually enabled. Eventhough it is listed in swlist; it may not yet be licensed. Run vxlicense -p to see if it is active. Also, let's not overlook the obvious; is this a vxfs system? Hfs filesystems cannot be extended while mounted. Also, are you trying to extend / or some other LVOL that requires contigious allocation.

Hi,

Sam does not support OnlineJFS. You'll have to use the command line options to extend a filesystem online.

lvextend -L new_size_in_mb /dev/vg_name/lv_name
fsadm -b new_size_in_KB /mount_point

for new_size_in_KB
bc
new_size_in_mb * 1024

Hope this helps.

I have used sam many times to extend the file system with OnLineJFS in 11.23, and I think 11.11 too. Is it possible a patch is needed?
