Question 1.
What are the steps to add a disk to a Sun Solaris host online (no reboot of the host)?

A. Drvconfig, disks
B. Drvconfig, format, label
C. Drvconfig, disks, devlinks
D. Vi sd.conf, touch /reconfigure, init 6

Answer: C

Explanation:
{From a SUN OS man page:} devlinks creates symbolic links from the /dev directory tree to the actual blockand character-special device nodes under the /devices directory tree. The links are created according to specifications found in the table-file (by default etc/devlink.tab). devlinks is called each time the system is reconfiguration- booted, and can only be run after drvconfig(1M) is run, since drvconfig(1M) builds the kernel data structures and the /devices tree.

Question 2.
Which three [3] characteristics do Veritas Volume manager, ALX LVM, HPUX LVM, and Solstice Disk Suite have in common?

A. Striping at the host level
B. Provides data protection
C. Places a unique label on each disk
D. Groups disks together in volume groups
E. Creates large volumes out of smaller disks

Answer: A, B, E

Explanation:
Volume Managers
Volume managers allow system administrators to perform operations on their physical devices at the operation-system level. Volume managers are typically used to provide flexibility that is not inherent in the file system or the storage system.

The operations commonly supported by volume managers fall into several categories:
1. Partitioning of LUNs into smaller logical devices
2. Aggregation of several LUNs into a larger logical device in order to provide a larger logical device
3. Striping of data across several LUNs in order to distribute I/O across many disks

A volume striped across LUNs where the LUNs themselves are striped across disks is also known as a plaid. {Page 14, CLARiiON Fibre Channel Storage Fundamentals, 10/31/2003)

Question 3.
Which component verifies that proper cabling has been done to the Katana?

A. SPS
B. Services Processor
C. LCC Loop ID LEDs
D. Fibre Channel Director

Answer: C

Explanation:
Katana refers to the Disk Array Enclosure (DAE2), which is a CLARiiON part. DAE2s connect to DPEs, SPEs or each other via LCCs (Link Control Cards). Thus the LCC Loop ID LEDs will indicate whether other not the enclosures are properly cabled together.
SPS= Standby Power Supply Fibre Channel Director is a Symmetrix component

Question 4.

Exhibit: *** MISSING ***

What does the "Alignment Offset" function align?

A. Lun on the raidgroup
B. Partition on the stripe boundary of a lun
C. Partition on the stripe size on the raidgroup
D. Partition on the metalun stripe element size

Answer: B

Explanation:
This (or alternately diskpar on Windows OSs) aligns the partition on the stripe boundary of a lun to prevent disk crossing. The typical stripe element size (128 blocks=64KB) is smaller than most I/O, so a crossing is more likely from a misaligned file system than a large I/O. This can have a significant impact upon disk performance.
Percent of data crossing = (I/O size)/(Stripe Element Size). A host-based utility (such as diskpar for Windows or fdisk for Linux) is preferred whenever there is array-based replication software in use such as SnapView, Replication Manager, etc.

Question 5.
What is a valid frontend SP ALPA address on CLARiiON FCC4700 series?

A. 0 - 124
B. 0 - 128
C. 0 - 224
D. 0 - 255

Answer: A

Explanation:
 
ALPA = Arbitrated Loop Private Address. Some addresses are reserved for the backend connections, thus the full 0-128 are not available for the front end.

Question 6.
Which 2 mirror drives are the boot disks for SPB on a CLARiiON CX600?

A. 0_0_0
B. 0_0_1
C. 0_0_2
D. 0_0_3

Answer: B. D

Explanation:
SP Boot Partitions - 2826.2 MB drives 0,1,2, & 3 - Each SP will have a mirrored SP boot partition. SPA will use drive 0 & 2 (0 is the primary with 2 as the mirror) and SPB will use drives 1 & 3 (1-primary, 3-mirror).

Question 7.
Which user account is needed to install drivers on UNIX servers?

A. sys
B. root
C. oracle
D. Administrator

Answer: B

Explanation:
Oracle and Administrator are not default user accounts on UNIX. Root is the master, all-powerful account in UNIX.

Question 8.
Why is a snapview session lost an SP failure?

A. The session was not persistent
B. The host agent was not running
C. The snapshot was not mounted
D. The snapshot was not in a storagegroup

Answer: A

Explanation:
Non-persistent sessions will not "trespass" over to the other SP. Options B, C, D have nothing to do with it.

Question 9.
Match the supported CLARiiON configurations. Choices may be used more than once.

Which command allows for the extraction of all lines containing EMC case insensitive from the file test txt?

A. vi test.txt
B. ed test.txt -EMC
C. grep EMC test.txt
D. grep -I emc test.txt

Answer: D
