Q31. What ACLs command would you use to stop the acslm process from accepting new requests?
B. stop req all
C. q requests now
D. requests wait
Explanation: Use this procedure to suspend request processing by putting ACSLS in the idle state. Typically, this procedure is used before shutting down ACSLS, but you can also use it to temporarily stop ACSLS request processing. To idle ACSLS, do the following:
1. From a cmd_proc, enter the following command:
ACSLS processes all current requests, rejects all new requests, and goes
into the idle state.
The following message appears when ACSLS request processing stops.
ACSLM Request Processing Stopped: Success.

Q32. When planning for partitioning the SL8500, which is NOT an assessment question?
A. How many partitions will there be in the library?
B. Is this a new or existing installation?
C. How many cartridges, free slots, and tape drives are needed for each partition?
D. How many CAP slots are needed for each partition?
Explanation: All HandBots and CAPs in the library are shared resources which cannot be assigned exclusively to one partition.
Q33. 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.
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)

Q34. ACSLS and the database MUST be in what mode to accomplish a restore?
A. Both stopped
B. ACSLS down, database up
C. ACSLS up, database down
D. Both running
Explanation: To restore the ACSLS database from the default tape device attached to the ACSLS server after a databasefailure, do the following:
3. Shut down the database:
4. Ensure any existing redo log files are available to the database system.
5. Make sure the most current backup tape is write-protected, then insert it into the tape device.
6. Enter the following command:
Depending on the nature of the database problem, the utility may prompt you for additional information.
7. Wait for the following prompt:
After performing a successful Oracle database recoveryyou should do a database backup. This will ensure yourability to recover again should you have another databasefailure. Do you want to do this database backup now?
8. Remove the tape from the drive and insert a new backup tape.
9. Enter "y"and press Return to start the backup.
10. Wait for the backup to complete. Remove the tape from the drive, write protect it, label it with the currentdate, and store it in a safe place.
11. To start ACSLS, enter the following command:
Q35. In what manner should libraries be added to SL8500 for nondisruptive growth of a library complex?
A. from left to tight, when facing the front doors
B. from right to left, when facing the front doors
C. from either side, It does not matter
D. only from the left
Explanation: Adding SL8500 Libraries to theLeft
When you add libraries to the left of an existing library complex, you can dynamically upgrade the configuration of the software (ACSLS or HSC). This upgrade must be done to configure the LSMs, panels, cells, and tape drives in the new libraries.
Note: Capacity for the SL8500 uses Capacity on Demand and RealTime Growth to allow you to instantly increase and activate capacity without disruption.

Q36. What steps would you use to clear all tapes out of an LSM panel?
A. Run a “query vol all” and then issue a “move vol range” for all the volumes in that panel
B. Run a “query vol all” and then issue an individual “move” for each of the volumes in that panel.
C. Issue a “freeze” command then remove all the volumes manually.
D. Manually remove all the volumes and do a “db_command bkup” to update the database.
Thequery volumecommand displays the location of a cartridge.
specifies the volume to query orallfor all volumes.
To display all volumes in the library:
q volume all
Note2: moving.sh -f vol_list_file -t lsm_id...
. -f vol_list_file
The file containing the list of volumes to be moved.

Q37. Partitioning allows the SL3000 library to be divided for use by multiple .
A. Power Supplies
B. Storage Cells
Explanation: Library resources (cells, drives, and CAPs) are allocated to a partition for exclusive use by that partition. Storage cells, CAPs, and tape drives allocated to a partition can be used only by the hosts assigned to that partition.
Storage cells, CAPs, and drives not allocated to, reserved for or associated with any partition cannot be accessed by any hosts.

Q38. An SL500 base module and one full DEM (including CAPs) has a maximum of how many slots and how many drives?
A. 150 slots and 4 drives
B. 158 slots and 6 drives
C. 143 slots and 6 drives
D. 100 slots and 4 drives
Note: Customers can purchase additional capacity in the following increments:
*FullBase – All storage cells in the Base Module.
*FullCEM – All storage cells in a cartridge expansion module (CEM).
*FullDEM – All storage cells in a drive expansion module (DEM).
*ThirdDEM – One-third of the storage cells in a DEM. For two-thirds of a DEM,
you would install two ThirdDEM. For all of a DEM, you could install three ThirdDEMs or one FullDEM.
Q39. Which feature contributes most to improved performance and higher library availability with the SL8500?
A. Redundant Control Cards
C. Redundant CAPs
D. Redundant Robots
Q40. 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
