switching controlers primary path

[Jason_309]

I would like to change the following around and make the primary the secondary and secondary primary.

/dev/dsk/c4t3d0 16384 16384
/dev/dsk/c6t11d0 16384 16384

vgreduce the primary path device
This will make the alternate the new primary

vgextend the just reduced disk
This will add it as an alternate

You can use "pvchange" to immediately set the primary disk:

pvchange -s /dev/dsk/c6t11d0


(no need to specify the VG)

But "pvchange -s" is only valid until next reboot, because /etc/lvmtab will remain unchanged.

I tried this on the a test and then do a vgdiplay and it shows the original disk as primary.

I tried the pvchange -s, but when i do a lvdisplay -v, it still shows the same disk as the primary disk.
