[j-nsp] cannot see hard disk

[Brendan Mannella]

The command he is referring to is...


>From shell, as root, check the boot devices

sysctl -a | grep bootdevs

(You will most likely see this) machdep.bootdevs: pcmcia-flash,compact-flash,lan

 
(at prompt, copy and paste this to put the HD back in the boot order) sysctl -w machdep.bootdevs: pcmcia-flash,compact-flash,disk,lan

Repeat  'sysclt-a | grep bootdevs' to ensure that it was changed.

If it happens again, there is most likely something wrong with the hard disk which seems to be common on the M7i, then your options are to RMA the RE if you have support, if not you can replace with a SSD drive.

Hope this helps.

If your system booted without the hard disk, it is likely the hard disk was
removed from the boot order.  If the hard disk was removed from the boot
order, it won't show up in "show chassis hardware details" (at least in my
experience).  It probably won't even show up in the boot messages.  However,
that does not mean that the hard disk is permanently destroyed, defective,
etc.; rather, it just means that the system detected an error (whether
transient or fatal) and stopped using it (including removing it from the
boot order).

I believe there is at least one way to re-add it to the boot order; however,
it involves dropping down to the shell (and, therefore, is not "supported"
without JTAC blessing).  You should probably contact the JTAC for help.
