Solaris 10 with Veritas and PowerPath

Hello,

I have an issue with veritas volume manager version 5.0 in combination with EMC powerpath version 5.2.0 running on Solaris10(Sparc). This server is fiber connected to a EMC Clariion CX3-40 SAN.

This is the situation :

Server is a SUN Enterprise M5000
OS = Solaris10 Sparc
Veritas Volume Manager = 5.0
EMC Powerpath = 5.2.0
SAN = EMC Clariion CX3-40

Problem description :

The server contains already a lot of LUNS which are available and seen by Powerpath and Veritas without a problem.
When i want to add a new LUN i follow these steps :

-create LUN on SAN
-Add it via powerpath
powermt display dev=all (device is not seen)
powermt config
powermt display dev=all (device is available)
powermt save

-configure controller commands
cfgadm -c configure c1
cfgadm -c configure c2

-Format disk
format < /dev/null (powerpath device available)
format <powerpath-device>
disk
label
ver

-vx commands
vxdisk list (volume not available)
vxdctl enable
vxdisk list (volume still not available)

And here is the problem that veritas doesn't see my new LUN untill i add an 2nd new lun, then he can see the 1st one i created, if i then want to see the 2nd LUN in need to add a 3rd one and so on.

Does anyone of you guys has experience with it and is there a way to solve it without a reboot of that server as this is a critical production machine.

Thanks in advance for youre reply's.
Kind regards,
Nico

sg_emc_trespass

SG_EMC_TRESPASS(8)						     SG3_UTILS							SG_EMC_TRESPASS(8)

NAME

       sg_emc_trespass - change ownership of SCSI LUN from another Service-Processor to this one

SYNOPSIS

       sg_emc_trespass [-d] [-hr] [-s] [-V] DEVICE

DESCRIPTION

       sg_emc_trespass	sends  an EMC-specific Trespass Command to the DEVICE with the selected options. This Mode Select changes the ownership of
       the LUN of the device from another Service-Processor to the one the command was received on.

OPTIONS

       Arguments to long options are mandatory for short options as well.

       -d     outputs some extra debug information associated with executing this command

       -hr    Sets the 'Honor Reservation' bit in the command. If set, the trespass will only succeed to change the ownership from the Peer SP	if
	      the Peer SP does not have an outstanding SCSI reservation for the LUN. By default, the reservation state will be ignored.

       -s     Send the short version of the trespass command instead of the long version. The short version is supported on the EMC FC5300, FC4500
	      and FC4700. The long version (default) is supported on the CLARiiON CX and AX family arrays.

       -V     print out version string then exit.

       In the 2.4 series of Linux kernels the DEVICE must be a SCSI generic (sg) device. In the 2.6 series block devices (e.g. SCSI disks and  DVD
       drives) can also be specified. For example "sg_start 0 /dev/sda" will work in the 2.6 series kernels.

EXIT STATUS

       The exit status of sg_emc_trespass is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
