2: Getting Started with Scali Manage
1. The installation of the compute node can either be a direct installation using
packages, or can be an installation using an installation image created from
another node, such as a service node. If the former method is used, it is possible
to use a compute node specific installation template.
2. Confirm that there is no
service-ib1:/home
NFS mount configured.
Confirm that there is no entry for
service-ib1:/home
in the
/etc/fstab
file
of the system from which the image is going to be created.
If this is the initial installation, then no
/home
entry is expected in the
/etc/fstab
of the compute node that is about to be imaged. However, if you are
not doing an initial installation, then this entry will exist in
/ec/fstab
. Delete
the
service-ib1:/home
entry from the node
/etc/fstab
file. There may be
other NFS entries included in
/etc/fstab
file that also need deleting, such as, a
service-ib1:/data
entry, or an entry or entries for off-cluster NFS servers.
3. Create an installation image from this node.
From the Altix ICE admin node, run the
scalimanage-cli captureimage
command. You can get a usage statement for this command, as follows:
scalimanage-cli help captureimage
captureimage <systemname> <imagename> [description] [excludes..]
Capture image from system
Arguments
systemname - name of system
imagename - name of image
description - Description of image; Default none
excludes - list of files or directories to be excluded (space separated)
Options:
--description=DESCRIPTION
To capture an image from node
r01i01n02
and save that image as
r01i01n02-image1
, perform the following:
scalimanage-cli captureimage r01i01n02 r01i01n02-image1
4. Configure the compute nodes to use this image.
scalimanage-cli help setdiskless
setdiskless <systemnames> <imagename>
This method sets systems(s) diskless with software image
