i have increase points as this is critical , my systems has been down for a week.our support with vendor has expired .
When did the storage disappear? What has happened/changed?!!
A) Starting lputil, you should see some status info message like this one:
# /usr/sbin/lpfc/lputil
LightPulse Common Utility for Solaris/SPARC. Version 1.6a8 (03/03/2004).
Copyright (c) 2003, Emulex Network Systems, Inc.
Emulex Fibre Channel Host Adapters Detected: 2
Host Adapter 0 (lpfc0) is an LP9K (Ready Mode)
Host Adapter 1 (lpfc1) is an LP9K (Ready Mode)
B) Check entries in /kernel/drv/lpfc.conf (bindings are defined here)
Do you know the WWNs of your Clariion storage?
Do you have a switch between host and storage or is it direct attached?
C) Also, please check your messages file if the emulex LP card did recognize the connection:
grep lpfc /var/adm/messages
grep lpfc /var/adm/messages.? (to check older files)
Cheers,
JustUNIX
Also, please tell us how your FC4700 is connected. I have an FC4700 hooked to a 2-node Solaris 8 (E450's) cluster with Veritas VCS and VEA through EMC/Brocade switches. I also have ECC (EMC Control Center) to monitor the physical health of the cluster. What is your configuration?
I also had a fibre cable crimped (might as well have cut it!) by people doing work around the storage cabinet. Was any work being done around your gear?
JustUNIX - I agree about where the problem undoubtedly lies (and also that dmesg output can be found in /var/adm/messages, but I like dmesg for recently-booted-system information). I was giving my system's config as an example.
kintos: Your FC4700 should have an administrative workstation with Navisphere on it. Can you reach the FC4700 through that (to check its health). You can ping it, so the 4700 is alive and well, to some degree.
By asking you to run 'dmesg' I was hoping to see output such as LUN acquisition:

Nov 3 11:17:28 DPH-DB002 genunix: [ID 936769 kern.info] sd191 is /pci@6,2000/fibre-channel@
and then up the boot process as the emcpower devices are loaded and acquired to the point where PowerPath loads:
Nov 3 11:19:49 DPH-DB002 PowerPath[83]: [ID 702911 daemon.notice] executing "powermt load"

Nov 3 11:20:08 DPH-DB002 genunix: [ID 454863 kern.info] dump on /dev/dsk/c0t0d0s1 size 4000 MB
I'm hoping the absence of a set of messages such as these will help localize the problem.
kintos - thanks for checking in with us. In addition to letting us know the status of LUN acquisition and powerpath from the last boot, let's check the status of your FC4700. Assuming you have powerpath, would you run the following commands? You will have to run them as root, and either be in or have /opt/EMCpower/bin/ in your path. I've enclosed short information so you can see what a functioning system looks like.

Could you see the storage before, and it went away?
If not, and you are adding storage, you need to first enable persistent binding in your HBA conf file (i.e. /kernel/drv/lpfc.conf) and then add the necessary luns to the /kernel/drv/sd.conf file. Then, you would do a boot -- -r to discover the disks.
