NCS 5508 - 7.3.2 - show tech-support files not found

[PatrickD]

At the request of the TAC I ran several show tech-support commands however despite the output from the command I cannot find the tech-support files anywhere in the file system.

In general show tech stores as per your mentioned location :

but in your case 

/misc/disk1//showtech/

can you post dir output ?

/misc/disk1 is the symlink for /harddisk, well actually both are for the real mount point. In the sysadmin VM you have to use harddisk: as not all of the linux hypervisor is exposed to the VM, IE that is the mountpoint provided to the VM.

First we need to make sure that the directories exist and are mounted properly:

If the showtech directory doesnt exist simply create it by 'mkdir /misc/disk1/showtech' then check it exists like below:

If you have a mount problem thats more complex and I would need to do a webex with you to find why the OS didn't mount the disk.

I am able to see the file in the directory as you demonstrated above, however when I try to connect to the router from our central FTP server which we use to download firmware, or upload show tech-support files I do not see the tech-support file in the same directory.

[smilstea · Accepted solution]

Sysadmin/admin does not have access to the interfaces in XR, there is a mgmt port dedicated to sysadmin but it probably isn't setup.

The easiest and most common thing to do is to copy the file over to the XR VM.

copy harddisk:/showtech/<file> harddisk: location 0/rp1/VM1

The key is that we need to copy to VM1 for the file to be copied between VMs.

Thanks, that worked.
