JUniper cihazlarda aşağıdaki hatayı alabilirsiniz.

Please re-install JUNOS to recover the primary copy in case it has been corrupted.

Bu durumda öncelikle alarmı doğrulayalım.

Şimdi partitionlara bakıp cihazın nereden boot olduğunu görelim.

ayhanarda@DC9-SW74> show system storage partitions
fpc0:
————————————————————————–
Boot Media: internal (da0)
Active Partition: da0s1a
Backup Partition: da0s2a
Currently booted from: backup (da0s2a)

Partitions information:
Partition Size Mountpoint
s1a 183M altroot
s2a 184M /
s3d 369M /var/tmp
s3e 123M /var
s4d 62M /config

Görüldüğü üzere backup partition unda çalışmakta , bunu aktif partitiona çekmeye çalışalım.

ayhanarda@DC9-SW74> request system snapshot slice alternate
fpc0:

Formatting alternate root (/dev/da0s1a)…
Copying ‘/dev/da0s2a’ to ‘/dev/da0s1a’ .. (this may take a few minutes)
The following filesystems were archived: /

Tamamlandığında cihazı restart edelim.

ayhanarda@DC9-SW74> request system reboot
Reboot the system ? [yes,no] (no) yes

Shutdown at Fri Mar 14 06:01:47 2014.

Cihazın açılması tamamlandıktan sonra tekrar bağlanıp bu kez sistemi nereden boot ettiğine tekrar bakalım , muhtemelen açılışta da yukarıdaki hatayı artık vermeyecektir.

ayhanarda@DC9-SW74> show system storage partitions

İşlem tamam gözüküyor.
