You need to set up an Oracle Solaris 11 host as an iSCSI target so that the host's disk can be accessed over a storage network. The disk device is c3t4d0.
Which six options describe the steps that need to be taken on this host to enable an iSCSI target?
A. Create a ZFS file system named iscsi/target.
B. Create a zpool named iscsi with disk device c3t4d0
C. Create zfs volume named iscsi/target.
D. Use the stmfadm command to create a LUN using /dev/zvol/rdsk/iscsi/target.
E. Use the stmfadm command to create a LUN using iscsi/target.
F. Use the stmfadm command to make the LUN viewable.
G. Use the stmfadm command to make the volume viewable.
H. Enable the svc:/network/iscsi/target:default Service.
I. Use the itadm command to create the iSCSI target.
Correct Answer: BCDFHI
How to Create an iSCSI LUN
The following steps are completed on the system that is providing the storage device. 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
Which two are implemented using the Internet Control Message Protocol (ICMP)?
A. ping
B. DHCP
C. HTTP
D. telnet
E. syslog
F. traceroute
Correct Answer: AF
The Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet Protocol Suite. ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between systems, nor is it regularly employed by end-user network applications (with the exception of some diagnostic tools like ping and traceroute).
Review the storage pool information: Choose the correct procedure to repair this storage pool.

A. Shut the system down, replace disk c3t3d0, and boot the system. When the system is booted, execute the zpool clear pool1 command.
B. Shut the system down, replace disk c3t3d0, and boot the system. When the system is booted execute the zpool online pool1 command.
C. Shut the system down, replace disk c3t3d0, and boot the system. When the system is booted, execute the zpool replace pool1 c3t3d0 command.
D. Shut the system down, replace disk c3t3d0, and boot the system. When the system is booted, execute the zpool replace pool1 c3t3d0 c3t3d0 command.
Correct Answer: C
You might need to replace a disk in the root pool for the following reasons:
The root pool is too small and you want to replace it with a larger disk
The root pool disk is failing. In a non-redundant pool, if the disk is failing so that the system won't boot,
you'll need to boot from an alternate media, such as a CD or the network, before you replace the root pool
disk.
In a mirrored root pool configuration, you might be able to attempt a disk replacement without having to
boot from alternate media. You can replace a failed disk by using the zpool replace command.
Some hardware requires that you offline and unconfigure a disk before attempting the zpool replace
operation to replace a failed disk.
For example:
# zpool offline rpool c1t0d0s0
# cfgadm -c unconfigure c1::dsk/c1t0d0
# cfgadm -c configure c1::dsk/c1t0d0
# zpool replace rpool c1t0d0s0
# zpool online rpool c1t0d0s0
# zpool status rpool
fs/zfs/bootblk /dev/rdsk/c1t0d0s0 x86# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t9d0s0
