To access the flash device on the adapter directly, type (all on one line)
oslpcfg directdownload a= filename> s= where s=1 saves the existing VPD. The following example accesses the flash device on an LPe12000 HBA: oslpcfg directdownload a=lpe12000 i=C:\image\ud100a8.rom s=1 The following example accesses the flash device if the offline utility cannot detect the adapter type and there is only one single-channel adapter or one dual-channel adapter in the system: oslpcfg directdownload a=default i=C:\image\ud100a8.rom s=1 Caution: In versions prior to 5.1 or with option s=0 in version 5.1,the ROM images used with the directdownload command may not contain certain VPD information (for example, serial number, adapter model, or manufacturer). Direct download of a ROM image that has not been confirmed to contain the correct VPD image updates the board's firmware, but it also clears the VPD. The board will function. If you use calls for VPD in your applications, the information may be changed or missing. World Wide Name Commands Writing WWN and Updating NVPARMS (writewwn) This command allows you to enter word 0 and word 1 of the WWPN or WWNN from the keyboard or a barcode scanner to update a specified adapter’s NVPARMS with a new WWPN or WWNN. The new WWPN and WWNN are used the next time the adapter is discovered. The adapter stores the original WWPN and WWNN in another region of the memory so it can be used to identify the adapter as it was manufactured. The WWN can also be read with a barcode scanner. The scriptwwnn and scriptwwpn commands use values entered with the command and can be used in a script file. Caution: Use the writewwn command with caution. If you use the same WWPN or WWNN on more than one adapter in a fabric, unpredictable results may occur. Note: Word 0 of WWNN and WWPN names must follow one of the following formats: 1 0 0 0 0 x x x 2 x x x x x x x 3 x x x x x x x 5 x x x x x x x To modify the WWPN and WWNN, type oslpcfg writewwn n=
The Write WWN prompts for the WWPN and WWNN cannot be used in a script file.
