I recently upgraded our DD640 to DDOS 22.214.171.124. It seemed to lose one of the bonds.
We have two bonded interfaces, veth2, bonded from eth1a and eth2a, and veth4, bonded from eth4a and eth4b. veth2 is our 10g network for backups, and veth4 is the front end.
veth4 lost the bond. It showed an ip assigned and everything, but no interfaces were assigned to it. I had to go through the backup network to ssh in. The user interface wasn’t available because we aren’t routing to the network, so I had to ssh in from the backup server.
I used the following command to add the interfaces back into the aggregate:
net aggregate add veth4 interfaces eth4a,eth4b mode lacp hash xor-L2L3
Once I did that, the interface came back up, and the DD640 was reachable through the UI.
I have been implementing EMC Networker at work, and I needed to pull tape volumes out of the library for offsite use. The documentation, page 224 of the Administrator Guide for 8.0, has a bunch of procedures, but they are listed through the gui. I looked up nsrmm and nsrjb to see what is required to export a volume.
To unload a volume from tape:
To mark a volume as offsite:
nsrmm -o offsite
To withdraw a volume to the Cartridge Access Port (CAP):
Then you can go to the library and export the volume and pull it out.
To import a volume, load it into the CAP, then type:
to deposit a tape from the CAP back into the library. You may need to inventory it afterwards using scanner:
There are other options available, such as specifying devices or slots. You can look at the man pages for nsrjb, nsrmm, and scanner for more details.
Another helpful command is nsrjb by itself. It will show a list of all the slots in the library and what volumes are in them. It doesn’t do a full inventory, just a list of what the networker thinks is in the library. If the information gets out of sync, you may have to re-initialize the library using the -H option, or maybe just rescan the inventory with the -I option.
