The Board Management software support board diagnostics. Please issue dis_diag to review the state of the card(s). If you have more than one card (host or target), please append '-a X' to specify which card you want to look at, where X is the adapter number - 0, 1, 2 or 3. These are assigned in sequence when the drivers are configured. Up to 4 cards is currently supported.
# dis_diag -a 0 (for the first card in a multi-card system) -----> Dis_diag will provide some information on the card; Adapter 0 > Type : PXH842 Mode : TRANSPARENT NodeId : 4 Serial number : PXH842-BC-000111 PXH chip family : PLX_DRACO_2 PXH chip vendorId : 0x10b5 PXH chip device : 0x8733 PXH chip revision : 0xCA EEPROM version : 05 EEPROM vendor info : 0x0000 Firmware version : 8.6 ...the slot-interface; Clock mode slot : Global Clock mode link : Global PCIe slot state : x16, Gen3 (8 GT/s) PCIe slot capabilities : x16, Gen3 (8 GT/s) ...and the status of the link from the card; Link 0 uptime : 84734 seconds Link 0 state : ENABLED Link 0 state : x16, Gen3 (8 GT/s) Link 0 required : x16, Gen3 (8 GT/s) Link 0 capabilities : x16, Gen3 (8 GT/s) ...If this host-card is connected to a supported target-card, dis_diag (-a 1) for that card would then show the target card; Adapter 1 > Type : PXH842 Mode : TARGET ...and show the cable-link as Link 0, and then the state of its slot as the slot; PCIe slot state : x8, Gen3 (8 GT/s) PCIe slot capabilities : x16, Gen3 (8 GT/s) (...) Link 0 state : x16, Gen3 (8 GT/s) Link 0 required : x16, Gen3 (8 GT/s) Link 0 capabilities : x16, Gen3 (8 GT/s) ...as above.
The slot and link-states can be checked to verify that the transparent connection is operating as expected. Dis_diag can also extract PCIe event-counters from the supported devices;
# dis_diag -a 0 -V 9 No of uncorrectable slot error events ......... : 0 No of correctable slot error events ........... : 0 (...) No of uncorrectable link error events ......... : 0 No of correctable link error events .......... : 0 ...and details on these; Uncorrectable error cnt - PCIe Cable Link 0 ... : 0 dlperr cnt ................................ : 0 sdoenerr cnt .............................. : 0 poisoned cnt .............................. : 0 fcperr cnt ................................ : 0 (etc)
To reset the PCIe error counters, please run dis_diag with the option -clear.
