Can't boot from SAN

[Vorb]

I've prepared new LUN for the nPar to move from local disks, changed primary boot path and get en error: 

Cannot find IODC data bytes.  Error Status: -4

Seach doesn't see anything except for local disks, but booted OS discovers LUN fine. 

I've found some document discribing that my FC card supports boot from san, but in chasis logs i see an error "BOOT_PDC_IODC_HEADER_ERR" which means that my card is either unsupported, or installed incorrectly. My card: 

# ioscan -funCfc
Class     I  H/W Path    Driver S/W State   H/W Type     Description
===================================================================
fc        0  0/0/12/0/0  fcd  CLAIMED     INTERFACE    HP AB378-60101 4Gb Single Port PCI/PCI-X Fibre Channel Adapter (FC Port 1)
                        /dev/fcd0

Maybe experienced administrators have some ideas how to fix this problem?

Seems to be an old firmware:
