fixed it !!!! miracle

right after alot of messing around i also upgraded the microcode for the fc adapters.

still didnt fix problem.

had another look at the IBM website specifically http://www-1.ibm.com/support/docview...=utf-8&lang=en

this has the devices.sdd.53.rte driver but version 1.6.0.0 not 1.6.2.0.

so unmount fs on san
deactivated vg on san
removed vpaths and then hdisks relevant to san
unistalled ver 1.6.2.0 and installed ver 1.6.0.0
cfgmgr -vl fcsX on both my adapters
then cfallvpath

redid the lsvpcfg and got:
vpath0 (Avail pv crm_train_vg) 00623296 = hdisk2 (Avail ) hdisk16 (Avail )
vpath1 (Avail pv crm_train_vg) 00723296 = hdisk3 (Avail ) hdisk17 (Avail )
vpath2 (Avail pv crm_train_vg) 00823296 = hdisk4 (Avail ) hdisk18 (Avail )
vpath3 (Avail pv crm_train_vg) 10723296 = hdisk5 (Avail ) hdisk19 (Avail )
vpath4 (Avail pv crm_train_vg) 10823296 = hdisk6 (Avail ) hdisk20 (Avail )
vpath5 (Avail pv ) 10D23296 = hdisk7 (Avail ) hdisk21 (Avail )
vpath6 (Avail pv crm_train_vg) 20723296 = hdisk8 (Avail ) hdisk22 (Avail )
vpath7 (Avail pv crm_train_vg) 20823296 = hdisk9 (Avail ) hdisk23 (Avail )
vpath8 (Avail pv crm_train_vg) 20923296 = hdisk10 (Avail ) hdisk24 (Avail )
vpath9 (Avail pv ) 20D23296 = hdisk11 (Avail ) hdisk25 (Avail )
vpath10 (Avail pv crm_train_vg) 30723296 = hdisk12 (Avail ) hdisk26 (Avail )
vpath11 (Avail pv crm_train_vg) 30823296 = hdisk13 (Avail ) hdisk27 (Avail )
vpath12 (Avail pv crm_train_vg) 30923296 = hdisk14 (Avail ) hdisk28 (Avail )
vpath13 (Avail pv ) 30D23296 = hdisk15 (Avail ) hdisk29 (Avail )

Now all the vpaths are Avail - LUN id's were always the same so was always looking at the correct data which i'd proved earlier by the fact that the VG was variedon and fs was working.

But now it all looks correct.

What i need to figure out is the difference between the two versions.

1.6.0.0 is supposed to be used if using the VIOS ( Warning: SDD version 1.6.1.0 or later is not supported by the VIOS at this time. )
So i can only assume that i am indeed using the Virtual I/O server although the info for the later drivers i.e 1.6.2.0 says that i should be able to use it with ESS.

Either way it is now working perfect.

thanks for the help anyway though people. Hopefully this will be useful to someone in the future.

iprupdate

IPRUPDATE(8)						      System Manager's Manual						      IPRUPDATE(8)

NAME

       iprupdate - IBM Power RAID adapter/device microcode update utility

SYNOPSIS

       iprupdate

       iprupdate --debug --check_only --daemon --use-polling --use-uevents

DESCRIPTION

       iprupdate  is used to update the microcode on IBM storage adapters and the disk units attached to them to a minimum supported level. It can
       be run at any time while the ipr device driver is loaded. The utility will check the microcode revision level of each storage  adapter/disk
       unit  on  the  system  and  compare  it	to  the  microcode  revision  level  that  is installed in /etc/microcode, /usr/lib/microcode, and
       /lib/firmware.  If the microcode level on the adapter/device is below the minimum supported level and the level	of  the  latest  image	is
       newer, the microcode will be updated to the latest level available. It is desired that this be called in the boot process.

OPTIONS

       --version
	      Print the version number of iprupdate

       --debug
	      Enable additional error logging. Enabling this will result in additional errors logging to /var/log/messages.

       --check_only
	      Check if any adapters or disk units are below their minimum supported level.

       --daemon
	      Run as a daemon to handle adapters and devices being hotplugged.

       --use-polling
	      Do not use netlink/uevent notification, but rather poll for adapter and device configuration changes.

       --use-uevents
	      Use  netlink/uevent notification rather than polling for adapter and device configuration changes. If not specified, polling will be
	      used until the first uevent notification appears, then netlink will be used.
