If the cabling is correct -and a loop circuit is completed, you should see "Monitor"; otherwise, -"LoopFail" (on open circuit) or some LPSM number/state with bit 3 set. - - -ERRATA: -1. Normally, Linux Scsi queries FC devices with INQUIRY strings. All LUNs -found according to INQUIRY should get READ commands at sector 0 to find -partition table, etc. Older kernels only query the first 4 devices. Some -Linux kernels only look for one LUN per target (i.e. FC device). - -2. Physically removing a device, or a malfunctioning system which hides a -device, leads to a 30-second timeout and subsequent _abort call. -In some process contexts, this will hang the kernel (crashing the system). -Single bit errors in frames and virtually all hot plugging events are -gracefully handled with internal driver timer and Abort processing. - -3. Some SCSI drives with error conditions will not handle the 7 second timeout -in this software driver, leading to infinite retries on timed out SCSI commands. -The 7 secs balances the need to quickly recover from lost frames (esp. on sequence -initiatives) and time needed by older/slower/error-state drives in responding. -This can be easily changed in "Exchanges[].timeOut". - -4. Due to the nature of FC soft addressing, there is no assurance that the -same LUNs (drives) will have the same path (e.g. /dev/sdb1) from one boot to -next. Dynamic soft address changes (i.e. 24-bit FC port_id) are -supported during run time (e.g. due to hot plug event) by the use of WWN to -SCSI Nexus (channel/target/LUN) mapping. - -5. Compaq RA4x00 firmware version 2.54 and later supports SSP (Selective -Storage Presentation), which maps LUNs to a WWN. If RA4x00 firmware prior -2.54 (e.g. older controller) is used, or the FC HBA is replaced (another WWN -is used), logical volumes on the RA4x00 will no longer be visible. - - -Send questions/comments to: -Amy Vanzant-Hodge (fibrechannel@compaq.com) - |
