Hi to all,
I've got fabrics configured with PID format 2 (Extended Edge ) FOS 5.0.3a .
I need to upgrade to release 6.xxx . The PID format 2 is not supported and I need to migrate to Core format .
What is the impact of the migration from format 2 to format 1 ???
As I understand , format 2 uses the same adressing model than native mode .
Is this the same as from native to core migration ?
I've got many HPUX and AIX hosts connected :-(
TIA , Reg/

Migrating from Extended Edge to Core PID implies a '-16' shift in Area byte, so you're right it's a lot of fun when there are many AIX and pre-11.31 HP-UX systems in the SAN.
One trick we used in our migration projects is to physically move storage connections to compensate Area change, e.g. move array ports connected to switch ports 0-3 to ports 16-19. As we need fabric-wide downtime to change PID format anyway, moving storage ports could be easier than reconfiguring a crowd of servers.
Hope this helps,
