Upgrading the routers
backup current system
To back up the file system to the removable USB drive, issue the following command:
user@host> request system snapshot media usb
Actually, you maye have to also partition the USB drive (it wants one DOS-style partition (BSD slice), inside which it creates several BSD partitions with disklabel)
request system snapshot media usb partition'''
If the partitioning fails, reboot the router and try again. If not, try to reboot the router with the usb stick in the router. I really hate to write this, but it seems like the BSD has trouble dealing with USB sticks.
install packages
Copy package from ftp server to local disk:
file copy ftp://root:xxx@10.11.102.64/tftpboot/remote/junos/9.1R2.7/junos-jsr-9.1R2.7-domestic.tgz /var/tmp/
Install:
request system software add /var/tmp/junos-jsr-9.1R2.7-domestic.tgz no-validate no-copy
Possible parameters for installation:
- no-validate/validate - Please always use no-validate for Voyager boxes.System will ensure rebootable for “validate”, which jsr images might do not work.
- no-copy - Remove backup
- unlink - Remote installation package
- reboot - remote after installation
Reboot the router when installing successfully:
request system reboot
You may free space on the compact-flash card by removing backup of the previos software version (YOU ALSO MAY NOT WANT TO DO THIS) request system software delete-backup
