In this case, I will be upgrading an SRX210H. This step is rather straight forward and If you require further clarification, please refer to the appropriate guide from Juniper Network’s Website.
First of all, Copy the JunOS Software into a USB FAT32 Formatted drive.
Make sure you have checked the integrity of the file by runnning md5sum, and compare it with the one listed on Juniper Network’s Website.
nish@WS /media/nish/JunOS $ md5sum junos-srxsme-11.4R9.4-domestic.tgz ac7a405477544d4a81b382f9816931d2 junos-srxsme-11.4R9.4-domestic.tgz nish@WS /media/nish/JunOS $
Go into the Shell prompt by issuing the command
nish@iNET> start shell if you are not already in there
Check the devices to see before plugging in the USB Drive containing JunOS.
% ls /dev/da* /dev/da0 /dev/da0s1c /dev/da0s2c /dev/da0s3e /dev/da0s4a /dev/da0s1 /dev/da0s2 /dev/da0s3 /dev/da0s3f /dev/da0s4c /dev/da0s1a /dev/da0s2a /dev/da0s3c /dev/da0s4 %
Plug in the USB Drive and you should see a similar message. As you can see the Device is da1
% umass1: CBM Flash Disk, rev 2.00/1.00, addr 4 da1 at umass-sim1 bus 1 target 0 lun 0 da1:
Removable Direct Access SCSI-2 device da1: 40.000MB/s transfers da1: 1001MB (2050560 512 byte sectors: 64H 32S/T 1001C)
Issue the following command again to see the partitions. This shows the JunOS is in
% ls /dev/da* /dev/da0 /dev/da0s2 /dev/da0s3c /dev/da0s4a /dev/da0s1 /dev/da0s2a /dev/da0s3e /dev/da0s4c /dev/da0s1a /dev/da0s2c /dev/da0s3f /dev/da1 /dev/da0s1c /dev/da0s3 /dev/da0s4 /dev/da1s1 %
Make the following Directory
/var/tmp/Flash and mount
/dev/da1s1 in there.
Make sure you are in root, otherwise it will not work.
root@iNET% mkdir /var/tmp/Flash/ root@iNET% mount_msdosfs /dev/da1s1 /var/tmp/Flash/
Check and confirm the file, then copy JunOS into
root@iNET% ls /var/tmp/Flash/ junos-srxsme-11.4R9.4-domestic.tgz root@iNET% cp /var/tmp/Flash/junos-srxsme-11.4R9.4-domestic.tgz /var/tmp/
Go into CLI
root@iNET% cli and issue the command
nish@iNET> request system software add /var/tmp/junos-srxsme-11.4R9.4-domestic.tgz no-validate no-copy partition unlink reboot
If all goes well, it should reboot with the newly install JunOS
