Example A-1 Collection Phase Examples
The following examples show how you might use the ldmp2v collect command.
Sharing an NFS-mounted file system. The following example shows the simplest way to perform the collect step where the source and target systems share an NFS-mounted file system.
As superuser, ensure that all required UFS file systems are mounted.
volumia# df -k
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c1t1d0s0 16516485 463289 15888032 3% /
/proc 0 0 0 0% /proc
fd 0 0 0 0% /dev/fd
mnttab 0 0 0 0% /etc/mnttab
/dev/dsk/c1t1d0s3 8258597 4304 8171708 1% /var

swap 4487448 16 4487432 1% /tmp

vandikhout:/u1/home/dana
6230996752 1051158977 5179837775 17% /home/dana
The following shows how to run the collection tool when the source and target systems share an NFS-mounted file system:
volumia# ldmp2v collect -d home/dana/volumia Collecting system configuration ... Archiving file systems ... Determining which filesystems will be included in the archive... Creating the archive... 895080 blocks Archive creation complete.
Not sharing an NFS-mounted file system. When the source and target systems do not share an NFS-mounted file system, the file system image can be written to local storage and later copied to the control domain. The Flash utility automatically excludes the archive that it creates.
volumia# ldmp2v collect -d /var/tmp/volumia Collecting system configuration ... Archiving file systems ... Determining which filesystems will be included in the archive... Creating the archive... 895080 blocks Archive creation complete.
Copy the Flash archive and the manifest file from the /var/tmp/volumia directory to the target system.
Skip file-system backup step. If backups of the system are already available using a third-party backup tool such as NetBackup, you can skip the file system backup step by using the none archiving method. When you use this option, only the system configuration manifest is created.
volumia# ldmp2v collect -d /home/dana/p2v/volumia -a none Collecting system configuration ... The following file system(s) must be archived manually: / /u01 /var
Note that if the directory specified by -d is not shared by the source and target systems, you must copy the contents of that directory to the control domain. The directory contents must be copied to the control domain prior to the preparation phase.
Example A-2 Preparation Phase Examples
The following examples show how you might use the ldmp2v prepare command.
The following example creates a logical domain called volumia by using the defaults configured in /etc/ldmp2v.conf while keeping the MAC addresses of the physical system:
# ldmp2v prepare -d /home/dana/p2v/volumia -o keep-mac volumia Creating vdisks ... Creating file systems ... Populating file systems ... Modifying guest domain OS image ... Removing SVM configuration ... Unmounting guest file systems ... Creating domain volumia ... Attaching vdisks to domain volumia ...
The following command shows information about the volumia logical domain:
# ldm list -l volumia
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
volumia inactive ------ 2 4G
NETWORK
NAME SERVICE DEVICE MAC MODE PVID VID
vnet0 primary-vsw0 00:03:ba:1d:7a:5a 1
DISK
NAME DEVICE TOUT MPGROUP VOLUME SERVER
disk0 volumia-vol0@primary-vds0
disk1 volumia-vol1@primary-vds0The following shows that you can completely remove a domain and its back-end devices by using the -C option:
# ldmp2v prepare -C volumia Cleaning up domain volumia ... Removing vdisk disk0 ... Removing vdisk disk1 ... Removing domain volumia ... Removing volume volumia-vol0@primary-vds0 ... Removing ZFS volume tank/ldoms/volumia/disk0 ... Removing volume volumia-vol1@primary-vds0 ... Removing ZFS volume tank/ldoms/volumia/disk1 ...
The following shows that you can resize one or more file systems during P2V by specifying the mount point and the new size with the -m option:
# ldmp2v prepare -d /home/dana/p2v/normaal -m /:8g normaal Resizing file systems ... Creating vdisks ... Creating file systems ... Populating file systems ... Modifying guest domain OS image ... Removing SVM configuration ... Modifying file systems on SVM devices ... Unmounting guest file systems ... Creating domain normaal ... Attaching vdisks to domain normaal ...
Example A-3 Conversion Phase Examples
The following examples show how you might use the ldmp2v convert command.
Using a network installation server. The ldmp2v convert command boots the domain over the network by using the specified virtual network interface. You must run the setup_install_server and add_install_client scripts on the installation server.
You can use the Custom JumpStart feature to perform a completely hands-off conversion. This feature requires that you create and configure the appropriate sysidcfg and profile files for the client on the JumpStart server. The profile should consist of the following lines:
install_type upgrade root_device c0d0s0
The sysidcfg file is only used for the upgrade operation, so a configuration such as the following should be sufficient:
name_service=NONE
root_password=uQkoXlMLCsZhI
system_locale=C
timeserver=localhost
timezone=Europe/Amsterdam
terminal=vt100
security_policy=NONE
nfs4_domain=dynamic
network_interface=PRIMARY {netmask=255.255.255.192
default_route=none protocol_ipv6=no}
For more information about using Custom JumpStart, see Oracle Solaris 10 9/10 Installation Guide: Custom JumpStart and Advanced Installations.

Using an ISO image. The ldmp2v convert command attaches the Oracle Solaris DVD ISO image to the logical domain and boots from it. To upgrade, answer all sysid prompts and select Upgrade.
Note - The answers to the sysid questions are only used for the duration of the upgrade process. This data is not applied to the existing OS image on disk. The fastest and simplest way to run the conversion is to select Non-networked. The root password that you specify does not need to match the root password of the source system. The system's original identity is preserved by the upgrade and takes effect after the post-upgrade reboot. The time required to perform the upgrade depends on the Oracle Solaris Cluster that is installed on the original system.

- Solaris Interactive Installation --------------------------------------------
This system is upgradable, so there are two ways to install the Solaris
software.
The Upgrade option updates the Solaris software to the new release, saving
as many modifications to the previous version of Solaris software as
possible. Back up the system before using the Upgrade option.
The Initial option overwrites the system disks with the new version of
Solaris software. This option allows you to preserve any existing file
systems. Back up any modifications made to the previous version of Solaris
software before starting the Initial option.
After you select an option and complete the tasks that follow, a summary of
your actions will be displayed.
