SRX

Hey all,

I have 2 SRX240H units that are standalong both doing the same thing where I can't upgrade them past 12.1X44-D60.2

I had one in production running 12.1X46-D72.2 3 days ago. I rebooted it to enable IPv6 and it never came back.

Ran 

set security forwarding-options family inet6 mode flow-based
request system reboot

On boot it is saying: 

panic: Error: Failed to find a valid wired memory profile

From loader I couldn't get it to boot, so I decided to reinstall it 

install file:///junos-srxsme-12.1X46-D72.2-domestic.tgz

It produced:

loader> install file:///junos-srxsme-12.1X46-D72.2-domestic.tgz

To skip a whole bunch of code, the only one that worked was junos-srxsme-12.1X44-D60.2-domestic.tgz

I can boot that version fine. But from Junos or loader, I can't load any other version above that one, not even junos-srxsme-12.1X45-D10-domestic.tgz

I also tried (from Junos) 

request system software add /tmp/usb/junos-srxsme-12.1X45-D10-domestic.tgz no-copy no-validate partition

And same error on boot (Failed to find a valid wired memory profile)

So I have no idea what I'm doing wrong or why I can't upgrade these units.

Whilst they are Just the SRX240H (not the H2) they do have 2GB memory so they should be supported (according to https://www.juniper.net/support/downloads/?p=srx240 and https://kb.juniper.net/InfoCenter/index?page=content&id=KB21476#srx_series) through to 12.1X46-D77

Any ideas or help appreciated. 

Hi, if your SRX240H's has 2 GB of RAM, they have been modified as SRX240H is only a 1G platform. Some people has tried to upgrade with 2 GB of memory - some with luck, other not.

Please validate that you actually have two SRX240's with 2G RAM. If so, then it's quite unsupported and difficult to help.

Ref. https://michaeldale.com.au/archive/2014/08/23/running-junos-121x47-on-first-gen-srx240h/ - especially some of the comments.

A script has been updated to prevent users from 2G branch-series platforms from upgrading to 12.1X46-D66 and later releases through PR 1264117.

Hence your upgrade fails. Please review the following TSB17084 for more informatoin:

https://kb.juniper.net/InfoCenter/index?page=content&id=TSB17084

12.1X46-D65 is the final maintenance release in 12.1X46 that is available for the 2GB RAM H/w.

Hey All

Karan, I don't think that is the case. That article is saying that support for 1GB models is extended, not stopped

Jonas, you hit the nail on the head.

Whilst the 2GB is unsupported, it works with the older releases. 

I rolled back to the 1GB and it worked perfectly for the upgrades........ here is the kicker but

After the upgrade is done (12.1X46-D60) I popped the 2GB back in, and it worked perfectly. 3 reboots later and its working fine still. 

I have a feeling something is doing a check on the memory on boot and halting it in some situations.

So for anyone who finds this later, its yeah, a memory issue.
