Q: A5200 on MDS 9509

I am having problem connecting an SUN A5200 JBOD to a MDS 9509. The port remains operative down:

# do show interface fc 3/2

fc3/2 is down (Link failure or not-connected)

Port description is A5200 Port A

Hardware is Fibre Channel, FCOT is short wave laser

Port WWN is xx:yy:zz:0d:ec:01:f9:80

Admin port mode is FL

Port vsan is 1

Receive data field Size is 2112

Beacon is turned off

5 minutes input rate 0 bits/sec, 0 bytes/sec, 791 frames/sec

5 minutes output rate 0 bits/sec, 0 bytes/sec, 0 frames/sec

695295 frames input, 0 bytes

0 discards, 0 errors

0 CRC, 0 unknown class

0 too long, 0 too short

2 frames output, 80 bytes

0 discards, 0 errors

0 input OLS, 0 LRR, 0 NOS, 20868 loop inits

0 output OLS, 0 LRR, 0 NOS, 4 loop inits

0 receive B2B credit remaining

0 transmit B2B credit remaining


As you can see, loop inits come in but nothing goes out. Cabling and port has been checked and changed.

What am I doing wrong?

Has this Jbod ever been connected to fabric switch, or just direct connect to a SUN host. Reason I ask is I recall a proprietary storage method SUN had with there Host HBA's

No - it has not been connected to a fabric switch. However data on the discs may get lost anyway - and I do not see a way to configure the A5200 box other than the normal FCAL way.

Additional Info: In the "link Errors" Tab on the device manager i found the counter BBCreditTransitionFromZero to increment with about 50 counts per second.

I believe the zero BB credit at init time is normal. I like you to open a Case with Cisco TAC so we can debug and get details on the A5200 you have.
