Oracle 1z0-820 - Upgrade to Oracle Solaris 11 System Administrator

ai_manifest

- Automated installation manifest file format

Synopsis

/usr/share/install/ai.dtd.1

Some customizations have been made, such as the selection of specific locales.

The dispadmin command displays or changes process scheduler parameters while the system is running.

-c class

Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fair-share class, and FX for the fixed-priority class. The time-sharing and inter-active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.

-g

Gets the parameters for the specified class and writes them to the standard output.

dlstat show-aggr [-r | -t] [-i interval] [-p] [ -o field[,...]] [-u R|K|M|G|T|P] [link]

Display per-port statistics for an aggregation.

A: To rename the bge0 link to mgmt0, enter the following command:

# dladm rename-link bge0 mgmt0

E: Consider that the bge0 device, whose link was named mgmt0 as shown in the previous example, needs to be replaced with a ce0 device because of a hardware failure. The bge0 NIC is physically removed, and replaced with a new ce0 NIC. To associate the newly added ce0 device with the mgmt0 configuration previously associated with bge0, enter the following command:

# dladm rename-link ce0 mgmt0

Note: How to Rename a Datalink

Use this procedure if you want to change a datalink name to a customized name. For example, some of the datalinks in upgraded system might have retained legacy hardware-based names and you want to change these names to generic ones.

Note: dladm rename-link [-R root-dir] link new-link

Rename link to new-link. This is used to give a link a meaningful name, or to associate existing link configuration such as link properties of a removed device with a new device.

 In this Solaris release, you can use the zpool split command to split a mirrored storage pool, which detaches a disk or disks in the original mirrored pool to create another identical pool.

After the split operation, import the new pool.

B: The Network Status notification icon is only displayed on the desktop if you are using NWAM to automatically configure your network.

C: All online (Wireless)

Indicates all manually enabled connections in the enabled network profile are online and that the required number of connections in the enabled profile group (if such a group exists) are online. The required number is the same as those described for the All online (Wired) status.

Note that at least one online connection is wireless.

A: ZFS encryption was introduced in ZFS Pool Version Number 30, Solaris Nevada b149.

Filesystem encryption since Solaris 11 Express

B: Deduplication was introduced in ZFS Pool Version Number 21, Solaris Nevada b128.

E: Booting From a ZFS Root File System

Both SPARC based and x86 based systems use the new style of booting with a boot archive, which is a file system image that contains the files required for booting. When a system is booted from a ZFS root file system, the path names of both the boot archive and the kernel file are resolved in the root file system that is selected for booting.

There is no data-link named vswitch192.168.

We need to create an etherstub first.

See Note and example below for details.

Note: Create a VNIC in the system's global zone.

# dladm create-vnic -l data-link vnic-name

data-link is the name of the interface where the VNIC is to be configured.

-l link, --link=link

link can be a physical link or an etherstub.

vnic-name is the name that you want to give the VNIC.

For example, to create a VNIC named vnic0 on interface e1000g0, you would type the following:

# dladm create-vnic -l e1000g0 vnic0

Example: Creating a Virtual Network Without a Physical NIC

First, create an etherstub with name stub1:

# dladm create-etherstub stub1

Create two VNICs with names hello0 and test1 on the etherstub. This

operation implicitly creates a virtual switch connecting hello0 and

test1.

# dladm create-vnic -l stub1 hello0

# dladm create-vnic -l stub1 test1

How to Create an iSCSI LUN

The disk volume provided by the server is referred to as the target. When the LUN is associated with an iSCSI target, it can be accessed by an iSCSI initiator.

The following tasks are completed on the system that is providing the storage device.

1. Install the COMSTAR storage server software.

target# pkg install storage-server

Etc.
