1. Disable and re enable the port from the switch management GUI 6 LILO is not Supported The LILO Boot Loader on i386 and x86_64 architectures is not supported for this driver stream If the LILO boot loader is used after the LPFC driver package is installed and upon reboot an incorrect initial ramdisk is used The system may not boot correctly Emulex Corporation Technical Support Phone 800 854 7112 Part Number P003754 01A Rev A Page 2 of 4 10 11 X EMULEX Workaround Use the GRUB boot loader This is the default boot loader for most of the Linux distributions Issue with the LPFC module order in the INITRD MODULES list On the SLES10 SP1 system if another SCSI driver such as aic79xx is loaded right after the LPFC driver through the initrd image an interruption might occur in the SCSI mid layer discovery process on the LUNs connected to LPFC s Fibre Channel This interruption can prevent the release of the SCSI discovery reference count and the LPFC driver cannot unload Workaround Do not add SCSI drivers right after the LPFC module in the INITRD_MODULES list The LPFC driver may not finish discovery when two initiator ports are swapped This causes all devices accessible through one or both of these initiator ports to time out and all I O to fail Workaround Do one of the following e When swapping cables replace each cable one at a time and allow for discovery to complete before replacing the next cable To de2.
