Для соединения делаем такой кабелёк: Serial Console Com Port; 2 – 2 3 – 3 5 – 5 The exact procedure is the following Details On 8Gb Brocade switches, if the Boot PROM password is not set(or it is set and known) and need to recover root password (in case it was set previously and forgotten), then follow the below procedure to set all the passwords to factory default (Factory defined user IDs: root, factory, admin and user, Default password: password): 1. Connect the serial console to the SAN switch (or director). (Default serial console settings: Baud rate – 9600, Data bits – 8, Parity – none, Stop bits -1, Flow control – none). 2. Reboot the switch 3. Press ESC at the message “Hit ESC to stop autoboot: “, the Boot PROM menu displays with the following options: 1) Start system. 2) Recover password. 3) Enter command shell. Option? 4. Type “3” to Enter Command shell. 1) Start system. 2) Recover password. 3) Enter command shell. Option? 3 Boot PROM password has not been set. => 5. Run the “printenv” command to check the environment variables (This step is optional). Sample output of “printenv” from a Brocade 8Gb switch: => printenv AutoLoad=yes BootromVerbose=no InitTest=MEM() LoadIdentifiers=Fabric Operating System;Fabric Operating System OSLoadOptions=quiet OSLoader=ATA()0x8c047;ATA()0x14e978 OSRootPartition=hda1;hda2 SkipWatchdog=yes baudrate=9600 bootcmd=setenv bootargs mem=${mem} ${OSLoadOptions};ataboot;bootm 0x400000 bootdelay=20 ethact=ppc_4xx_eth0 ethaddr=00:05:1E:5B:4D:C3 hostname=sequoia initrd_high=0x20000000 mem=520192k preboot=echo;echo Type "run flash_nfs" to mount root filesystem over NFS;echo netdev=eth0 consoledev=ttyS1 ramdiskaddr=400000 ramdiskfile=your.ramdisk.u-boot stderr=serial stdin=serial stdout=serial ver=U-Boot 1.1.3 (Apr 15 2008 - 19:19:34) Environment size: 631/4080 bytes Sample output of “printenv” from a Brocade 4Gb switch: > printenv AutoLoad=yes ENET_MAC=00051E0343E3 InitTest=MEM() LoadIdentifiers=Fabric Operating System;Fabric Operating System OSLoadOptions=quiet;quiet OSLoader=ATA()0x3c020;ATA()0x6b348 OSRootPartition=hda1;hda2 SkipWatchdog=yes 6. Set the environment variable “OSLoadOptions” to single (or –s) => setenv OSLoadOptions single (Note: On 4Gb switches, the setenv requires “=” as well: setenv OSLoadOptions=single ) 7. Run “printenv” command to verifyt the new value of “OSLoadOptions”: => printenv AutoLoad=yes BootromVerbose=no InitTest=MEM() LoadIdentifiers=Fabric Operating System;Fabric Operating System OSLoadOptions=single OSLoader=ATA()0x8c047;ATA()0x14e978 OSRootPartition=hda1;hda2 SkipWatchdog=yes baudrate=9600 bootcmd=setenv bootargs mem=${mem} ${OSLoadOptions};ataboot;bootm 0x400000 bootdelay=20 ethact=ppc_4xx_eth0 ethaddr=00:05:1E:5B:4D:C3 hostname=sequoia initrd_high=0x20000000 mem=520192k preboot=echo;echo Type "run flash_nfs" to mount root filesystem over NFS;echo netdev=eth0 consoledev=ttyS1 ramdiskaddr=400000 ramdiskfile=your.ramdisk.u-boot stderr=serial stdin=serial stdout=serial ver=U-Boot 1.1.3 (Apr 15 2008 - 19:19:34) Environment size: 652/4080 bytes 8. Run the command “boot” ( on 4 Gb switches, run the command “auto”) => boot Note: The rest of the steps are same for all switches with Linux based FOS (ver 4.1 and above). 9. After the switch boot in single user mode, remount the / partition as read/write: sh-2.04# mount -o remount,rw,noatime / 10. Mount the second partition to /mnt (this will get from the value of “OSRootPartition” variable in “printenv” output – usually it will be “hda2”, that is, /dev/hda2) sh-2.04# mount /dev/hda2 /mnt 11. Verify the mounted file systems by running the “mount” command: sh-2.04# mount /dev/root on / type unknown (rw,noatime) none on /proc type proc (rw) none on /dev/pts type devpts (rw,mode=620) none on /tmp type ramfs (rw) /dev/hda2 on /mnt type ext3 (rw) 12. Run the “passwddefault” command as follows: sh-2.04# /sbin/passwddefault 13. Reboot the switch. sh-2.04# reboot –f After reboot, login to the switch using username “admin”, password “password” and set the new passwords for root, factory, admin and user accounts. For details about the other password recovery methods on Brocade SAN switches (and Directors) with Linux based FOS (FOS 4.1 and above), refer the engineering advisory: http://h41302.www4.hp.com/km/saw/view.do?docId=emr_na-c01227153-2 . For all types of password recovery methods on Brocade switches and Directors(except Boot PROM password recovery on 8Gb switches), refer the “Fabric OS Password Recovery Notes” from Brocade.
