DESCRIPTION

Logical objects of this type are stored in the xCAT database in one or more tables. Use the following commands to manipulate the objects: mkdef, chdef, lsdef, and rmdef. These commands will take care of knowing which tables the object attributes should be stored in. The attribute list below shows, in parentheses, what tables each attribute is stored in.


osimage Attributes:

addkcmdline (linuximage.addkcmdline)

User specified arguments to be passed to the kernel. The user arguments are appended to xCAT.s default kernel arguments. This attribute is ignored if linuximage.boottarget is set.

boottarget (linuximage.boottarget)

The name of the boottarget definition. When this attribute is set, xCAT will use the kernel, initrd and kernel params defined in the boottarget definition instead of the default.

bosinst_data (nimimage.bosinst_data)

The name of a NIM bosinst_data resource.

cfmdir (osimage.cfmdir)

CFM directory name for PCM. Set to /install/osimages/<osimage name>/cfmdir by PCM.

configdump (nimimage.configdump)

Specifies the type of system dump to be collected. The values are selective, full, and none. The default is selective.

crashkernelsize (linuximage.crashkernelsize)

the size that assigned to the kdump kernel. If the kernel size is not set, 256M will be the default value.

description (osimage.description)

OS Image Description

driverupdatesrc (linuximage.driverupdatesrc)

The source of the drivers which need to be loaded during the boot. Two types of driver update source are supported: Driver update disk and Driver rpm package. The value for this attribute should be comma separated sources. Each source should be the format tab:full_path_of_srouce_file. The tab keyword can be: dud (for Driver update disk) and rpm (for driver rpm). If missing the tab, the rpm format is the default. e.g. dud:/install/dud/dd.img,rpm:/install/rpm/d.rpm

dump (linuximage.dump, nimimage.dump)

The NFS directory to hold the Linux kernel dump file (vmcore) when the node with this image crashes, its format is "nfs://<nfs_server_ip>/<kdump_path>". If you want to use the node's "xcatmaster" (its SN or MN), <nfs_server_ip> can be left blank. For example, "nfs:///<kdump_path>" means the NFS directory to hold the kernel dump file is on the node's SN, or MN if there's no SN.

or

The name of the NIM dump resource.

The disk and partition that the Windows will be deployed to. The valid format is <disk>:<partition>. If not set, default value is 0:1 for bios boot mode(legacy) and 0:3 for uefi boot mode; If setting to 1, it means 1:1 for bios boot and 1:3 for uefi boot

isdeletable (osimage.isdeletable)

A flag to indicate whether this image profile can be deleted. This attribute is only used by PCM.

kerneldir (linuximage.kerneldir)

The directory name where the 3rd-party kernel is stored. It is used for diskless image only.

The version of linux kernel used in the linux image. If the kernel version is not set, the default kernel in rootimgdir will be used

kitcomponents (osimage.kitcomponents)

List of Kit Component IDs assigned to this OS Image definition.

osupdatename (osimage.osupdatename)

A comma-separated list of OS distro updates to apply to this osimage.

partitionfile (linuximage.partitionfile, winimage.partitionfile)

The path of the configuration file which will be used to partition the disk for the node. For stateful osimages,two types of files are supported: "<partition file absolute path>" which contains a partitioning definition that will be inserted directly into the generated autoinst configuration file and must be formatted for the corresponding OS installer (e.g. kickstart for RedHat, autoyast for SLES). "s:<partitioning script absolute path>" which specifies a shell script that will be run from the OS installer configuration file %pre section; the script must write the correct partitioning definition into the file /tmp/partitionfile on the node which will be included into the configuration file during the install process. For statelite osimages, partitionfile should specify "<partition file absolute path>"; see the xCAT Statelite documentation for the xCAT defined format of this configuration file.

or

The path of partition configuration file. Since the partition configuration for bios boot mode and uefi boot mode are different, this configuration file can include both configurations if you need to support both bios and uefi mode. Either way, you must specify the boot mode in the configuration. Example of partition configuration file: [BIOS]xxxxxxx[UEFI]yyyyyyy. To simplify the setting, you also can set installto in partitionfile with section like [INSTALLTO]0:1

permission (linuximage.permission)

The mount permission of /.statelite directory is used, its default value is 755

pkgdir (linuximage.pkgdir)

The name of the directory where the distro packages are stored. It could be set multiple paths.The multiple paths must be seperated by ",". The first path in the value of osimage.pkgdir must be the OS base pkg dir path, such as pkgdir=/install/rhels6.2/x86_64,/install/updates . In the os base pkg path, there are default repository data. And in the other pkg path(s), the users should make sure there are repository data. If not, use "createrepo" command to create them.

pkglist (linuximage.pkglist)

The fully qualified name of the file that stores the distro packages list that will be included in the image. Make sure that if the pkgs in the pkglist have dependency pkgs, the dependency pkgs should be found in one of the pkgdir

postbootscripts (osimage.postbootscripts)

Comma separated list of scripts that should be run on this after diskfull installation or diskless boot. On AIX these scripts are run during the processing of /etc/inittab. On Linux they are run at the init.d time. xCAT automatically adds the scripts in the xcatdefaults.postbootscripts attribute to run first in the list. See the site table runbootscripts attribute.

postinstall (linuximage.postinstall)

The fully qualified name of the script file that will be run at the end of the genimage command. It is used for diskless image only.

postscripts (osimage.postscripts)

Comma separated list of scripts that should be run on this image after diskfull installation or diskless boot. For installation of RedHat, CentOS, Fedora, the scripts will be run before the reboot. For installation of SLES, the scripts will be run after the reboot but before the init.d process. For diskless deployment, the scripts will be run at the init.d time, and xCAT will automatically add the list of scripts from the postbootscripts attribute to run after postscripts list. For installation of AIX, the scripts will run after the reboot and acts the same as the postbootscripts attribute. For AIX, use the postbootscripts attribute. See the site table runbootscripts attribute. Support will be added in the future for the postscripts attribute to run the scripts before the reboot in AIX.

profile (osimage.profile)

The node usage category. For example compute, service.

provmethod (osimage.provmethod)

The provisioning method for node deployment. The valid values are install, netboot,statelite,boottarget,dualboot,sysclone. If boottarget is set, you must set linuximage.boottarget to the name of the boottarget definition. It is not used by AIX.
