NAME

nodemedia - Manage server remote media

SYNOPSIS

nodemedia <noderange> [attach|detachall|list|upload] [options] <media>

DESCRIPTION

nodemedia manages the remote media functionality of supported BMCs.

list shows all the current remote media the BMCs of the noderange are providing to the host platform. The string (insecure) is appended to URLs that are mounted in an insecure fashion. http is insecure, and https is also insecure when no meaningful certificate validation is performed. Currently there is no action that can change this, and this is purely informational. A future version of software may provide a means to increase security of attached remote media. If no media is mounted, this will provide no output, error conditions will result in output to standard error.

detachall removes all the currently provided media to the host. This unlinks remote media from urls and deletes uploaded media from the BMC.

upload takes the given media image and uploads it to the BMC. This causes the remote media to reside internally to the system without having to go to the network after the upload. This is more constrained, for example the Lenovo xClarity Controller has a limit of 50 megabytes, but it has zero ongoing load on the media source.

attach takes a URL to a remote media as an argument, and has the given BMCs map a virtual USB device to that url. Content is loaded on demand, and as such that URL is referenced potentially once for every IO operation that the host platform attempts.

EXAMPLES

Listing currently mounted media
# nodemedia s1-s4 list
s1: boot.img
s2: boot.img
s4: boot.img
Uploading a small boot image to the BMC
# nodemedia s1-s4 upload boot.img
s1:complete: 100% s2:complete: 100% s3:complete: 100% s4:complete: 100%
s1: boot.img
s4: boot.img
s2: boot.img
Attaching a larger ISO for on-demand access
# nodemedia s1,s4 attach http://172.30.0.6/install/rhel74.iso
s4: http://172.30.0.6/install/rhel74.iso (insecure)
s1: http://172.30.0.6/install/rhel74.iso (insecure)
