None
Handling Process
Step 1  Run a command to check whether the physical link is normal. If the link status is displayed to be 1, the link is normal.
VIS_7796_0:/OSM/ISM/CLI # osp_mml fc gs
Speed: 1-1G,2-2G,4-4G
Mode: 1-ini,2-tgt,3-both,4-m_ini,8-m_tgt,c-m_both
Link: 0-null, 1-good, 2-down wait, 3-down confirm
Port: 0 Speed:0[4] Mode:3 Link:1 Name:22000022a100dbac Bus: 5 Host:3 Sfp:4300 IO:155
Port: 1 Speed:0[2] Mode:3 Link:1 Name:22010022a100dbac Bus: 5 Host:4 Sfp:4300 IO:259
Port: 2 Speed:0[1] Mode:3 Link:3 Name:22020022a100dbac Bus: 5 Host:5 Sfp:4300 IO:0
Port: 3 Speed:0[1] Mode:2 Link:1 Name:22030022a100dbac Bus: 5 Host:0 Sfp:4300 IO:0
Port:10 Speed:0[4] Mode:3 Link:1 Name:22040022a100dbac Bus:11 Host:7 Sfp:4300 IO:81
Port:11 Speed:0[2] Mode:3 Link:1 Name:22050022a100dbac Bus:11 Host:8 Sfp:4300 IO:600
Port:12 Speed:0[4] Mode:3 Link:3 Name:22060022a100dbac Bus:11 Host:9 Sfp:4300 IO:0
Port:13 Speed:0[1] Mode:3 Link:2 Name:22070022a100dbac Bus:11 Host:13 Sfp:4300 IO:0
Step 2  Remove the VIS FC cables. Wait 10 seconds and plug the FC cables to check whether the negotiation is successful.
Step 3  Set the FC port to auto-adaptive mode by using the ISM or CLI. The CLI command is as follows:
chgfcspeed -c controller ID -i interface ID -p port ID -s 0
Repeat step 1 to check whether the link is normal.
Step 4  Run a command under debug to reset the VIS FC port. The port number is 0.
VIS_7796_0:/OSM/ISM/CLI # osp_mml fc pl 0

0     22000022a101a017 1    6  1  1   0      1       5714
Total used 1, free 2559
Repeat step 1 to check whether the link is normal.
Root Cause
In most cases, the hardware is normal. The fault can be removed by modifying relevant parameters or resetting the port.
