Troubleshooting DEVICES (Disk drives) are NOT found (IBM DS4000 specific) by NetWare: If NSSMU can not find any devices (disk drives) for you to turn into LUNs, check these things: 1] Did you assign the storage LUNs to the correct HBA addresses? 2] Did you reboot or rescan for hardware changes on the NetWare host after you assigned the storage LUNs to this NetWare host? 3] Did you remember to change the HBAs LUNS PER TARGET from 0 to 256? If it is zero, the NetWare host will never see any data LUNs. An alternate method for setting the LUNS PER TARGET for QLogic HBAs to to add the command line parameter /MAXLUNS=256 to the LOAD QL2X00.HAM command in STARTUP.NCF (use the NWCONFIG utility to modify STARTUP.NCF. 4] Are you invoking LOAD QL2X00.HAM with the /LUNS /ALLPATHS /PORTNAMES parameters? (scroll to the bottom) 4] Are the LUNs of type NETWARE FAILOVER (in IBM's DS4000 Storage Manager)? 5] Is the AVT failover bit set to AVT OFF ("zero")? There is usually a script called something like SET AVT OFF that can be run on the controllers.
