NS120 is working fine (both SPA, SPB & data movers), but the control station , is unable to boot . I connected a keyboard and a screen to analyze the messages :
Creating root device
Mounting root filesystem
mount: error 6 mounting ext3
mount: error 2 mounting none
switching to new root
switchroot: mount failed 22
mount /initrd/dev failed :2
Kernel panic - not syncing attempted to kill init !
When trying to boot from CD , i found the BIOS was protected by a password (??) . then i was unable to boot from CD.
How could we recover the control station to a normal state , many thanks in advance.
the problem has been solved, many thanks to an EMC expert from Algeria who suggested to boot with NAS CD , when having a boot issue on the control station , you must know that booting with any Redhat linux CD will not work , the only CD that works was NAS CD that was shipped with Celerra.
