To verify device recognition: 1. Log in to the system as root. 2. Display the device data to verify that the system recognizes the newly installed devices on the disk array. Use the ioscan -fn command to display the device data. On a system with a large LUN configuration, HP-UX may not build device files on all LUNs. Enter insf -e to build all missing device files. Example # ioscan -fn Class I H/W Path Driver S/W State H/W Type... bc 6 14 ccio CLAIMED BUS_NEXUS... fc 1 14/12 fcT1 CLAIMED INTERFACE... lan 2 14/12.5 fcT1_cntl CLAIMED INTERFACE... fcp 1 14/12.8 fcp CLAIMED INTERFACE... ext_bus 6 14/12.8.0.0.0 fcpmux CLAIMED INTERFACE... disk 4 14/12.8.0.0.0.0.0 sdisk CLAIMED DEVCE... disk 5 14/12.8.0.0.0.0.1 sdisk CLAIMED DEVICE... ext_bus 7 14/12.8.0.255.0 fcpdev CLAIMED INTERFACE... target 10 14/12.8.0.255.0.0 tgt CLAIMED DEVICE... ctl 5 14/12.8.0.255.0.0.0 sctl CLAIMED DEVICE... In the example: • HP OPEN-9 device: SCSI bus number = 14/12, bus instance = 6, SCSI target ID = 0, LUN = 0. • HP OPEN-9*2 device: SCSI bus number = 14/12, bus instance = 6, SCSI target ID = 0, LUN = 1. • If UNKNOWN is displayed for a disk, the HP 9000 system may not be configured properly. Refer to the HP documentation or contact HP customer support for assistance with the HP 9000 system or the HP-UX operating system. 3. Enter the device data for each disk array device in a table.
