the CF is not mandatory; we have two M7is running 9.3R2 without the
benefit of CF. (the routers are fully redundant for each other which
is how we sidestep the redundant RE issue.)
however, depending on what version you upgrade from you might see
a dramatic increase in RAM utilization. in our case, we upgraded from
8.5 and saw RAM utilization go from around 70-74% to over 90%. this
is on RE-400s with 768 MB RAM, each with a full route view. we are
now awaiting delivery of recently purchased RE-850s with 1536 MB RAM. :-)

I don't think it is, though the recommendations aren't clear.
If you have a flash card, it has to be 1GB, rather than 256MB, but I don't
think having a flash card is mandatory (but it is advisable, particularly in an
M7i, which only has one RE)

Subject: Re: [j-nsp] New flash card in M7i
So what is the reason, that the flash card as primary boot device is
now obligatory?

Once installed, your router won't boot from it, since it's blank, so
will boot from HD as normal. Then you should be able to issue
'request system snapshot partition' (ie. copy main contents of hard
disk to flash drive). From that point on, the CF will be your primary
boot medium. Any code upgrades from then on will occur on the CF
card, so to back up that code and config in the future, you'd issue
'request system snapshot' to copy them to the HD, which is now your
'alternative' boot medium.

Hi!
I would like to add a new 1 GB CF card in a M7i. I assume, there is
none in
that device at the moment:
Filesystem Size Used Avail Capacity
Mounted on
/dev/ad1s1a 217M 98M 102M 49% /
devfs 1.0K 1.0K 0B 100% /dev

/dev/md8 504M 470K 463M 0% /mfs
/dev/ad1s1e 24M 20K 22M 0% /config
procfs 4.0K 4.0K 0B 100% /proc
/dev/ad1s1f 18G 542M 16G 3% /var
So I need one to update to 9.3R2.
Do I have to prepare the CF before injecting it into the router?
Does it
have to be formatted?
Regards,
Matthias
