=== Images based on CentOS 7.3 ===

These images are based on the default image from Bright Cluster Manager.

Clone the default image to "new" name
<code>
 [bright1->softwareimage]% clone default-image compute-image
 [bright1->softwareimage]% clone default-image login-image
 [bright1->softwareimage]% clone default-image sched-image
</code>

Clone the default category to a "new" category
<code>
 [bright1->category]% clone default compute
 [bright1->category]% clone default login
 [bright1->category]% clone default scheduler
</code>

Set the default software image for each category
<code>
 [bright1->category*[compute*]]% set softwareimage compute-image
 [bright1->category*[login*]]% set softwareimage login-image
 [bright1->category*[scheduler*]]% set softwareimage sched-image
 [bright1->category*]% commit
</code>

=== Images based on CentOS 6.7 ===

* Install CentOS 6.7 manually on a physical machine [hostname "iml"]

* Copy ssh-keys from Bright server to the physical machine

<code>
 [root@bright1 ~]# ssh-copy-id root@172.18.0.187
 [root@bright1 ~]# ssh root@172.18.0.187 
 Last login: Sun Aug 13 18:47:05 2017 from master.cm.cluster 
 [root@iml ~]#
</code>

* Copy CentOS 6 repo for Bright manager and dell repository

<code>
 [root@bright1 general_repos]# scp cm.repo 172.18.0.187:/etc/yum.repos.d/cm.repo
 [root@bright1 general_repos]# scp dell-osma-repository.repo 172.18.0.187:/etc/yum.repos.d/dell-osma-repository.repo
</code>

* Install additional packages for dependencies on the physical machine
<code>
 [root@iml ~]# yum groupinstall -y "development tools" [gives me rsync, perl etc]
 [root@iml ~]# yum install redhat-lsb-core  [cmd init script requires it]
 [root@iml ~]# yum install smartmontools  ["smart" healthcheck fails without it]
</code>

* Create image from the physical machine 

<code>
 [root@bright1 images]# cm-create-image --fromhost 172.18.0.187 --imagename iml-image --hwvendor dell

* Clone iml-image to create "new" images of it

<code>
 [bright1->softwareimage]% clone iml-image mds-image
 [bright1->softwareimage]% clone iml-image oss-image
 [bright1->softwareimage]% clone iml-image nfs-image
 [bright1->softwareimage]% commit
</code>

* Clone default category and set software images for each category

<code> 
 [bright1->category]% clone default mds
 [bright1->category[mds]]% set softwareimage mds-image
 [bright1->category*[mds*]]% commit
 [bright1->category[mds]]% exit
 [bright1->category]% clone default oss
 [bright1->category[oss]]% set softwareimage oss-image
 [bright1->category*[oss*]]% commit
 [bright1->category[oss]]% exit
 [bright1->category]% clone default nfs
 [bright1->category*[nfs*]]% set softwareimage nfs-image
 [bright1->category*[nfs*]]% commit
 [bright1->category[nfs]]% exit
 [bright1->category]% clone default iml
 [bright1->category*[iml*]]% set softwareimage iml-image
 [bright1->category*[iml*]]% commit
