1z0-820 Exam Dumps - Oracle Solaris 11 System Administrator Questions and Answers

 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.

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.

zonep2vchk

- check a global zone's configuration for physical to virtual migration into non-global zone

The zonep2vchk utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone.

The p2v process involves archiving a global zone (source), and then installing a non-global zone (target) using that archive

zonep2vchk serves two functions. First, it can be used to report issues on the source which might prevent a successful p2v migration. Second, it can output a template zonecfg, which can be used to assist in configuring the non-global zone target.

zonep2vchk can be executed on a Solaris 10 or later global zone. To execute on Solaris 10, copy the zonep2vchkutility to the Solaris 10 source global zone.

When run on Solaris 10, a target release of S11 can be specified, which will check for p2v into a Solaris 10 Branded zone.

How to Create an iSCSI LUN

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

• 1.Create a ZFS storage pool.

Example: target# zpool create sanpool mirror c2t3d0 c2t4d0

(C)2. Create a ZFS volume to be used as a SCSI LUN.

(D)3. Create a LUN for the ZFS volume.

Example:

target# stmfadm create-lu /dev/zvol/rdsk/sanpool/vol1

Logical unit created: 600144F0B5418B0000004DDAC7C10001

4. Confirm that the LUN has been created.

Example

target# stmfadm list-lu

LU Name: 600144F0B5418B0000004DDAC7C10001

(F) 5. Add the LUN view.

This command makes the LUN accessible to all systems.

target# stmfadm add-view 600144F0B5418B0000004DDAC7C10001

How to Create the iSCSI Target

This procedure assumes that you are logged in to the local system will contains the iSCSI target.

Note: The stmfadm command manages SCSI LUNs. Rather than setting a special iSCSI property on the ZFS volume, create the volume and use stmfadm to create the LUN.

(H) 1. Enable the iSCSI target service.

target# svcadm enable -r svc:/network/iscsi/target:default

(I) 2. Create the iSCSI target.

target# itadm create-target

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.
