I am planning to do online storage migration following below steps, it has one ldom.
  1. Remove 1 fc
  2. Assign the luns from the new storage
  3. scan the devices
  4. Mirror it ( dont know the command )
  5. Break the mirror and remove the old storage lun
  6. attach the 2nd fc.

Will this work ?

hpfc(7D)							      Devices								  hpfc(7D)

NAME

       hpfc - Agilent fibre channel host bus adapter

SYNOPSIS

       PCI   pci103c

DESCRIPTION

       The hpfc fibre channel host bus adapter is a SCSA compliant nexus driver that supports all Agilent fibre channel host bus adapters, includ-
       ing the HHBA5100x, HHBA5101x, and HHBA5121x models. Agilent host bus adapters support the fibre channel protocol on private  fibre  channel
       arbitrated loops and fabrics. The driver supports up to ten host bus adapters, with a maximum of 125 fibre channel devices on each host bus
       adapter. The hpfc driver supports a maximum of 256 LUNs per target.

       The hpfc driver does not support the BIOS Int 13 feature, which enables the booting of an operating system. As a  result,  you  should  not
       install an operating system on devices attached to the hpfc driver.

CONFIGURATION

       The hpfc driver attempts to configure itself using the information in the /kernel/drv/hpfc.conf configuration file.

       By default, the driver supports only LUN 0 for each target device. To add multiple LUN support, modify the /kernel/drv/sd.conf file.

       Before  upgrading the hpfc driver, backup the sd.conf file to save customized LUN settings and then use pkgrm(1M) to remove the old version
       of the driver.

       The host bus adapter port is initialized to FL_Port when connected to a fabric switch. To change it  to	F_Port,  add  the  init_as_nport=1
       entry to the hpfc.conf file and reboot the system.

       To  conserve system resources, at least one disk drive must be attached to the hpfc driver. If no devices are attached, the driver will not
       load.
