Q31. Which four statements are true for an SL8500?
A. Partitioned LSMs will not recognize other LSMs, within the library unless they are in the same partition.
B. The elevator operationisunder the control of the library controller when CAP operations are issued.
C. CAPS can either be shared or dedicated resources for partitions.
D. All drives, storage slots, and cartridges within a partition are solely owned by that host or host group.
E. While duplicate VOLSERs are supported by the library, ACSLS does not support duplicate VOLSRs unless they are in different partitions and the duplicate VOLSERs are on different ACLs servers.
Answer: B,C,D,E
Explanation:
B:Elevator operation is under the control of the library controller when CAP operations are issued. The library controller uses the elevators and HandBots to access the entire capacity of the CAPs for enters and ejects without regard for the partitions.
Note: Elevators provide vertical pass-thru operations between rails within the same library. Both elevators are located in the front of the library between the front access doors and the Service Safety Door. Each of the four rails share the two elevators.
C: Partitions share the ownership of the CAPs. That is, if one host/partition has CAP A reserved, a different host/partition can have CAP B reserved, or one host/partition can have both CAPs reserved.
D: Elevators, robots, and CAPs are shared resources and—each partition can fully use shared resources for cartridge movement, enter, and eject operations. All drives, storage slots and cartridges within a partition are solely owned by that host or host group.
E: Duplicate VOLSERs are supported by the library; however, ACSLS and HSC do not, unless: *The duplicate VOLSERs are in different partitions.
* With HSC managed partitions, the duplicate VOLSERs are in different control data sets.
* With ACSLS managed partitions, the duplicate VOLSERs are managed by different ACSLS servers.
Note. volume serial numbers (VOLSERs)

Q32. Identify two recommendations for utilizing the top rail of SL8500.
A. Use the top rail to support applications with active enters and ejects.
B. Use the top rail as an archival LSM for less active tapes.
C. Use the top rail to support applications with very active tapes but few enters and ejects.
D. Avoid using the top rail as an archival location.
Answer: B,C
Explanation: Tape cartridges can be archived to a rail without tape drives.
A suggestion would be to use the top rail for these scenarios.
Example: inactive volumes, least recently used (LRUs) volumes, or volumes that require few enter and eject operations.

Q33. When mapping tape application workloads to the SL8500 rails, a maximum of one workload assigned to each rail.
A. True
B. False
Answer: B
Explanation: The SL8500 is not just another library. Each SL8500 has four separate rails or Library Storage Modules (LSMs) that work together in parallel.
There can also be two robots operating concurrently on each rail. This architecture offers extremely flexible and scalable configurations that can simplify automated tape applications. Instead of distributing cartridges and tape drives evenly across all the rails, look at it from a business perspective and logically configure each individual rail to meet your specific needs and business requirements. Allocate separate tape application workloads to specific LSMs (rails).

Q34. What is the procedure to restore ACSLS files and database to a prior time and date?
A. Log in as “root”, stop both ACSLS and the database, issue the “bdb.acsss –f ” command, and then select option # 1
B. Log in as “acsss”, stop both ACSLS and the database, enter a “rdb.acsss”, and then select option # 2
C. Log in as “acsss”, idle ACSLS, stop ACSLS, and then issue “rdb.acsss”
D. Log in as “acsss”, stop the database, enter an “db_command restore”, and then select option #
Answer: B
Explanation: In this procedure you restore the database to the most recent backup created on the local disk by automatic backups. ACSLS control files are also restored.
To restore a corrupted or lost database to the most recent backup:
1. Log in asacsss.
2. From the cmd_proc window, idle ACSLS:
idle
3. Shut down ACSLS:
kill.acsss
4. Shut down the database:
db_command stop
5. Enter the following command:
rdb.acsss
6. Select option 1: (we should use option 2, see note below)
1. Restore from a current local disk backup
7. To start ACSLS, enter the following command:
rc.acsss
Note:
rdb.acsss Menu Options
Please enter the number followed by Return for your choice from the following menu.
Press? followed by the Return key for help.
1: Restore from a current local disk backup
2: Restore from a previous tape or file backup
3: Restore database only (do not include ACSLS control files)
4: Restore only ACSLS non-database control files
E: Exit

Q35. To continue the install process, in which directory should the ACSLS install scripts be loaded?
A. /export/home/backup
B. /export/home/ACSSS/bin
C. /opt/StorageTek/ACSLS/install
D. /export/home/ACSSS/install
Answer: D
Explanation: Installing ACSLS Software via install.sh
1. Change directories: cd /export/home/ACSSS/install
2. To initiate the installation shell script, enter /install.sh
Etc.

Q36. Which of the items are reports available from SLC regarding partitioning on an SL500?
A. Cartridge Cell and Media Summary
B. Host Connections Summary
C. Orphaned Cartridge Report
D. Partition Summary
E. Partition Details
F. All of the above
Answer: F
Explanation: Partitions—Reports include: Partitions— Reports—Cartridge Cell and Media Summary Partitions—Reports—Host Connections Summary Partitions—Reports—Orphaned Cartridge Report Partitions—Reports—Partition Details Partitions— Reports—Partition Summary

Q37. Which three statements are accurate regarding physical and hardware activated capacity on the SL3000?
A. Physical and hardware activated capacity can be equal
B. Physical capacity can exceed hardware activated rapacity
C. Hardware activated capacity can exceed physical capacity
D. Physical and hardware activated capacity must be equal
Answer: A,B,C
Q38. What ACSLS command would change a cap priority?
A. set cap priority 5 0, 0, 1
B. define cap priority 5 0,0,1
C. change cap priority 5 0, 0, 1
D. lock cap priority 5 0, 0, 1
Answer: A
Explanation: A: The set cap priority command sets a CAP's automatic selection priority. Format set cap priority cap_priority cap_id

Q39. Which three items does the cartridge database of the SL3000 library controller maintain?
A. Volume ID
B. Date Entered
C. Current Location
D. Verified Status Answer: A,C,D
Explanation: An audit is the process of reading and cataloging cartridges within a library, verifying the locations of cartridges, or validating a range of slot locations. The library controller maintains a cartridge database that contains the following information for all the cartridges in the library:
* Volume ID (VOLID or volser)
* Current location (in library internal address format)
* Verified status (true or false)
