Use the rctladm command to enable the global action on the task.max-lwpa resource control.

Modify the /etc/syslog.conf file to activate system logging of all violations of task.max-lwps and then refresh then svc: /system/system-log:default service.

Activate system logging of all violations of task.max-lwpp in the /etc/rctldm.conf file and then execute the rctladm-u command.

Use the prct1 command to set the logging of all resource control violations at the time the task.max-lwps resource control is being setup.

Use the setrct1 command to set the logging of all resource control violations for the task.max-lwps resource control.

if there are any native non-global zones on the system that you want to migrate, these zones will be migrated into non-global zones on the Solaris 11 system

The non-global zone must reside on its own ZFS dataset; only ZFS is supported

The non-global zone can reside on a ZFS dataset or a UFS file system

The solarisl 0 branded zone can be either a sparse or a whole root non-global zone model.

The default is the exclusive-IP type.

When migrated from a stand-alone Solaris system to a solarisl 0 branded zone, the host ID changes to the host ID of the new machine The zone cannot be configured to use the host ID of the original system

A sparse root zone cannot be converted into a solarislO branded zone.

The encrypted file system must have been created in Oracle Solaris 11. To encrypt a ZFS file system from a previous version of Solaris, upgrade

the zpool and create a new encrypted ZFS file system in that zpool Finally, move or copy the data from the existing ZFS file system into the new encrypted ZFS file system.

if you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30, minimum.

ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

ZFS encryption requires that the ZFS Dataset Encryption package be installed.

E If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 21, minimum. D f Encryption is supported at the pool or dataset (file system) level

Encryption is supported at the pool level only and every file system in the pool will be encrypted.

Encryption is supported at the pool level only and every file system in the pool will be encrypted.

You cannot create an encrypted file system in a zpool that was created prior to Oracle Solaris 11.

Create a new zpool in Solaris 11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.

Create a local IPS repository on the AI Install server and start the repository server service, the publisher origin to the repository file.

Set up a IP address on the AI install server.

The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.

DHCP must be available on the network for the Install server and the clients, but the install server does not need to be the DHCP server.

Download the AI boot image. The image must be the same version as the Oracle Solaris OS that you plan to install on the client.

Download the text install image into the IPS repository.

Install the AI installation tools.

The service name is prod_ai.

DHCP base IP address is 192.168.1.100

The initial IP address for the install clients will be 192.168.1.100. This IP address is temporary. After the client is booted, it will use IP addresses in the following range: 192.168.1.101-105.

Five IP addresses are allocated for DHCP clients, starting with 192.168.1.100.

The Install server will support up to five clients.

A message will be logged with syslogd when the number of notice messages generated by the resource control threshold meets or exceeds the value specified with [count]

A message will be logged with sysloqd when the number of violations generated by the resource control threshold meets or exceeds the value specified with [count].

The global resource control monitoring for the task.max-lwps resource control has been enabled and syslog messaging for that resource control has been set to notice. However, because the [count] value has not been specified, there is no threshold set for the resource to monitor. The configuration to monitor the task.max-lwps resource control is incomplete.

You must set up DHCP. The DHCP server and Al install server can be the same machine or two different machines.

You can create only one manifest per install service. If you need more than one manifest, create multiple install services.

The minimum requirement to operate as an Al install server is 1 GB of memory.

If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS( then create two Al manifests and a single install service.

Load the install/installadm package on the Al server.

an Al SC profile for non-global zones

the default Al config file for non-global zones

the default Al manifest for non-global zones

a custom Al manifest

AJ: manifest files

JumpStart: begin script

iSCSI devices can be used as dump devices.

SCSI commands are carried over IP networks and enable you to mount disk devices from across the network onto your local system.

Large amounts of data can be transferred over an IP network with very little network degradation.

COMSTAR allows you to convert any Solaris11 host into a SCSI target device that can be accessed over a storage network.

One IP port can handle multiple ISCSI target devices.
