How can I find out which File system is controlled by what controller?

[Steven E. Protter]

Shalom,

Yes my logical analysis. There is no single command or report that will do this for you. There may be a well designed script that can.

ioscan

Take note of which disks are on which controller.

pvdisplay the disks.

Take a look at which logical volumes, therefore file systems on are on which disk.

bdf output should be used to confirm this.

Basically what u need to find which disks are controlled by which controller.
#bdf filesystem
will show you vg and lvol
#lvdisplay -v
you will see the disk name and from disk name u can find the controller name.
or ioscan -fnC disk|grep disk
will tell you exact information.

Anyways genrally you'll have a alternate link as well which u can see by vgdisplay -v vgname,

Hope this help,
BR,

"which File system is controlled by what controller"

This is just too general. A filesystem is not controlled by a controller.

A file system based on a LVOL can span multiple disks, each connected to a different disk controller.

Please try to explain again what you are looking for.

1>>>first list out on which all VG's does the file systems exists in.
2>>>then give vgdisplay for all those vg's
3>>>this vl tell you which PV is included in those VG's.

which would also tell you the Controller which is controlling those PV's.

it can also b alternate paths

which alternate paths used to access da PV is the controller controlling respective file system
