LDOM BASIC

1)How to Enable the Logical Domains Manager Daemon

# svcadm enable ldmd

# /opt/SUNWldm/bin/ldm list

2)Upgrading a System That Is Already Using Oracle VM Server for SPARC

1)Upgrade the system with the required system firmware. 2)Apply the required Oracle Solaris 10 OS patches or Oracle Solaris 11 OS SRU.

3)Save the configurations to the SP

3)Saving and Restoring Autosave Configuration Directories

1) Save the autosave directories

# cd /

# tar -cvpf autosave.tar var/opt/SUNWldm/autosave-*

2)to restore

/var/opt/SUNWldm

# tar -xvpf autosave.tar

4)Saving and Restoring the Logical Domains Constraints Database File

Whenever you upgrade the operating system on the control domain, you must save and restore the /var/opt/SUNWldm/ldom-db.xml Logical Domains constraints database file.

5)Upgrading the Logical Domains Manager and the System Firmware

1)Stop all domains

primary# ldm stop-domain -a

2) Issue the unbind-domain subcommand from the control domain for each domain.

primary# ldm unbind-domain ldom

6)How to Upgrade to the Oracle VM Server for SPARC 3.1 Software (Oracle Solaris 11)

Save your configuration to the SP.

# ldm add-config config-name

Create a snapshot of your existing BE

# beadm create snapshot-name

Create a backup BE based on the snapshot.

# beadm create -e snapshot-name BE-name

Install the Oracle VM Server for SPARC 3.1 version of the ldomsmanager package from the online software repository as part of an update to the latest SRU

# pkg update

Verify that the package is installed.

# pkg info ldomsmanager

Restart the ldmd service.

#svcadm restart ldmd

Verify that you are running the correct ldm version.

# ldm -V

Save your configuration to the SP

#ldm add-config ldoms-3.1-config

7)How to Remove All Guest Domains

Stop all domains

primary# ldm stop-domain -a

Unbind all domains except for the primary domain.

primary# ldm unbind-domain ldom

8)Destroy all domains except for the primary domain.

#ldm remove-domain -a

9)How to Restore the Factory Default Configuration

primary# ldm set-config factory-default

primary# shutdown -i5 -g0 -y

-> stop /SYS

-> start /SYS

23) Virtual Disk Assignment to Guest Domain:-

1)    Form File

2)    From slice

3)    From entire disk

4)    From Zvols (or) SVM vols (or) veritas volumes.VDISK TYPEZFSVeritasVTOCNoof Slices usableDynamic Space allocationFileyNy7ysliceyNN1yEntire Diskyyy7NZvolsyNy7y

24) How to Add a Virtual Disk

1)Export the virtual disk back end from a service domain

# ldm add-vdsdev [-fq] [options={ro,slice,excl}] [mpgroup=mpgroup] \

backend volume-name@service-name

2) Assign the back end to a guest domain

# ldm add-vdisk [timeout=seconds] [id=disk-id] disk-name volume-name@service-name ldom

25) How to Export a Virtual Disk Back End Multiple Times

1)Export the virtual disk back end two times from a service domain.

# ldm add-vdsdev [options={ro,slice}] backend volume1@service-name

# ldm add-vdsdev -f [options={ro,slice}] backend volume2@service-name

Note that the second ldm add-vdsdev command uses the –f option to force the second export of the back end.

Use this option when using the same back-end path for both commands and when the virtual disk servers are located on the same service domain.

2)Assign the exported back end to each guest domain.

The disk-name can be different for ldom1 and ldom2.

# ldm add-vdisk [timeout=seconds] disk-name volume1@service-name ldom1

# ldm add-vdisk [timeout=seconds] disk-name volume2@service-name ldom2

26)How to Change Virtual Disk Options online

# ldm set-vdsdev options=[{ro,slice,excl}] volume-name@service-name

27) How to Change the Timeout Option

# ldm set-vdisk timeout=seconds disk-name ldom

28)How to Remove a Virtual Disk

1.Remove a virtual disk from a guest domain.

# ldm rm-vdisk disk-name ldom

2.Stop exporting the corresponding back end from the service domain.

# ldm rm-vdsdev volume-name@service-name

29)How to Export a Physical Disk Slice as a Virtual Disk

primary# ldm add-vdsdev /dev/dsk/c1t57d0s0 c1t57d0s0@primary-vds0

primary# ldm add-vdisk pslice c1t57d0s0@primary-vds0 ldg1

ldg1# ls -1 /dev/dsk/c0d13s*

/dev/dsk/c0d13s0

/dev/dsk/c0d13s1

/dev/dsk/c0d13s2

/dev/dsk/c0d13s3

/dev/dsk/c0d13s4

/dev/dsk/c0d13s5

/dev/dsk/c0d13s6

/dev/dsk/c0d13s7

Although there are eight devices, because the disk is a single-slice disk, only the first slice (s0) is usable

To export slice 2 (disk c1t57d0s2, for example) you must specify the slice option. Otherwise, the entire disk is exported.

# ldm add-vdsdev options=slice /dev/dsk/c1t57d0s2 c1t57d0s2@primary-vds0

30)How to Export a File as a Full Disk

service# mkfile 100m /ldoms/domain/test/fdisk0

primary# ldm add-vdsdev /ldoms/domain/test/fdisk0 fdisk0@primary-vds0

primary# ldm add-vdisk fdisk fdisk0@primary-vds0 ldg1

ldg1# ls -1 /dev/dsk/c0d5s*

/dev/dsk/c0d5s0

/dev/dsk/c0d5s1

/dev/dsk/c0d5s2

/dev/dsk/c0d5s3

/dev/dsk/c0d5s4

/dev/dsk/c0d5s5

/dev/dsk/c0d5s6

/dev/dsk/c0d5s7

31)How to Export a ZFS Volume as a Full Disk

service# zfs create -V 100m ldoms/domain/test/zdisk0

primary# ldm add-vdsdev /dev/zvol/dsk/ldoms/domain/test/zdisk0 zdisk0@primary-vds0

primary# ldm add-vdisk zdisk0 zdisk0@primary-vds0 ldg1

ldg1# ls -1 /dev/dsk/c0d9s*

/dev/dsk/c0d9s0

/dev/dsk/c0d9s1

/dev/dsk/c0d9s2

/dev/dsk/c0d9s3

/dev/dsk/c0d9s4

/dev/dsk/c0d9s5

/dev/dsk/c0d9s6

/dev/dsk/c0d9s7

31)How to Export a ZFS Volume as a Single-Slice Disk

service# zfs create -V 100m ldoms/domain/test/zdisk0

primary# ldm add-vdsdev options=slice /dev/zvol/dsk/ldoms/domain/test/zdisk0 zdisk0@primary-vds0

primary# ldm add-vdisk zdisk0 zdisk0@primary-vds0 ldg1

ldg1# ls -1 /dev/dsk/c0d9s*

/dev/dsk/c0d9s0

/dev/dsk/c0d9s1

/dev/dsk/c0d9s2

/dev/dsk/c0d9s3

/dev/dsk/c0d9s4

/dev/dsk/c0d9s5

/dev/dsk/c0d9s6

/dev/dsk/c0d9s7

32)Exporting Volumes and Backward Compatibility

Add the following line to the /etc/system file on the service domain

set vds:vd_volume_force_slice = 1

Setting this tunable forces the export of all volumes as single-slice disks, and you cannot export any volume as a full disk

33)How to Configure Virtual Disk Multipathing

# ldm add-vdsdev mpgroup=foo backend-path1 volume@primary-vds0

# ldm add-vdsdev mpgroup=foo backend-path2 volume@alternate-vds0

# ldm add-vdisk disk-name volume@primary-vds0 ldom

After we configure the virtual disk with multipathing and start the guest domain, the virtual disk accesses its back end through one of the service domains it has been associated with.

If this service domain becomes unavailable, the virtual disk attempts to access its back end through another service domain that is part of the same multipathing group.
