Change SCSI card with SCSI ID 6 with FC card

[Woo Kim Chye]

Hi, we have 2 A-500 workstations that form a MCSG cluster. Both workstations are connected to a JBOD(A3312) disks using the SCSI cards with inline terminators. I have also changed the SCSI ID for SCSI cards in one of the server to 6 instead of the original 7.

Recently we just got ourselves 2 FC10. So we will replace the A3312 disks with the 2 FC10. Therefor we have to change the SCSI cards with the FC card. My question is, after I chage the SCSI card with SCSI ID 6 with the new FC card, what will be the SCSI ID for the FC card? Do I need to do any changes?

Thanks.

The SCSI ID has no influence on the FC host bus adapter. You don't have to change it

There is no SCSI ID for FC card. The FC cards have something called a world wide name (WWN)which is very analogous to the MAC address on an ethernet card.

All the FC card is having a unique World wide name which you can find out by fcmsutil command. The FC channels are not like the SCSI Channels . In single SCSI Channels you will find the device name changes like c1t1d0,c1t2d0 c1t3d0...c1t15d0. But in a FC Channel you will get like c1t1d0, c1t1d1, c1t1d2....c1t1d8.

Thanks for the reply. Just curious, when we change the SCSI id for the SCSI card, is the change stored in the bios for the server or the SCSI card itself.

hi,
The SCSI ID is only use in SCSI device,
and some FC device have dummy SCSI ID.
The FC device use WWN, that is just like MAC address in LAN card.

So U needn't do anything just replace the SCSI
Card with FC card. BTW, if U meet problem, pleas make sure U have installed the driver for the FC card.

Good luck TO U ! Meng

Hi,

Once you install a FC card you *will* need to
install the correct driver in order to use them.

For an A500 the card is product number A5158A.
There is software for this on your application
CD set. You can also download it if you can't
find it. You will also need to make sure that
you have the correct drivers installed in your
kernel. You can include these and build a new
kernel from SAM should you wish.

The server maintains a table with the hardware address, SCSI and SCSI transfer rate. This is stored in the NVRAM on the system card, not on the SCSI card
