Known Issues Routing Disable/Enable the Switch Port Use these steps to disable/enable the affected switch port. 1. Determine which path is missing using the show dev/full or sho dev/multi command. 2. After connecting to the switch via telnet, issue the command portdisable xx (where xx = the switch port number the HBA is plugged into) followed by portenable xx. Disconnect/Reconnect the affected HBA cable Use these steps to disconnect/reconnect the affected HBA cable. 1. Determine the affected HBA cable. 2. To disconnect/reconnect the HBA cable at the switch, issue the command per the following example: set dev $1$dga601:/switch/path=PGA0.5000-1FE1-5000-2DED, set dev $1$dga604:/switch/path=PGA0.5000-1FE1-5000-2DE8 Verify that Paths are Restored Issue the show dev/multi command to verify the paths are restored, as follows: VMS06>show dev /mul $1$DGA601: $1$DGA602: $1$DGA603: $1$DGA604: (VMS06) Mounted (VMS06) Mounted (VMS06) Mounted (VMS06) Mounted 1 4/ 4 PGA0.5000-1FE1-5000-2DED 0 4/ 4 PGB0.5000-1FE1-5000-2DEC 0 4/ 4 PGB0.5000-1FE1-5000-2DE9 1 4/ 4 PGA0.5000-1FE1-5000-2DE8 Regardless of how many E_Ports are connected between two switches, the maximum routing paths are currently limited to 16 E_Ports for the SAN Switch 2/32. The urouteshow command may occasionally indicate the wrong routing paths of I/O traffic. This is a problem with the urouteshow command, as I/O traffic is still routed correctly. 60 SAN switch 2/32 Version 4.0.2b Release Notes
