Questions 13

Two RDF groups from two PowerMax arrays have been added to a Consistency Group SRDF/A Multi-Session Consistency has been enabled for the Consistency Group. The RDF daemon has been started on a single host that has access to both the PowerMax arrays

What will happen if the host becomes unavailable?

Options:

Cycle switching will stop

RDF links will be suspended immediately

SRDF pair state will become Partitioned

SRDF mode will change to Adaptive Copy Disk

Options:

Minutes

Hours

Days

Weeks

Questions 15

From an application perspective what should be done prior to performing an SRDF Fallback operation?

Options:

Continue accessing the R2 devices

Start accessing the R1 devices before running the command

Stop accessing the R2 devices

Run the command and then start accessing the R1 devices

Stop accessing the R2 devices

Start accessing the R1 devices before running the command

Questions 16

What is the default size of a Gatekeeper on a PowerMax array?

Options:

3 cylinder

6 cylinder

6 KB

Questions 17

A storage administrator is using SE 10 to query a PowerMax 2000 using symcfg list -dir and wants to seethe number of Cores that are assigned to the front-end emulations

What does the storage administrator need to do?

Options:

Use the-mode v9x argument for backwards compatibility as some output has been deprecated

Look for CPU instead of Cores as these have been rebranded to allow differentiating between virtual and physical hardware.

Specify the full 12-digit serial number with -sidsoSE 10 understands the output relates to an older system model.

Use syraconf igure -version -dir as in SE 10 support for outputs specific to older systems moved to a different command.

Questions 18

What are the two configuration rules that apply to SRDF groups and connections during Non-Disruptive Migrations'?

Options:

The source and target arrays are at most one hop away from the control host

Two DM RDF groups are created per SG migration session

RF and RE ports are supported, with RF ports being selected if both types are available

A single array cannot have multiple DM RDF groups

DM RDF groups are configured with a minimum of one path

Answer:

A, E

Explanation:

Step by Step Comprehensive Detailed Explanation:

Non-Disruptive Migration (NDM) is a feature in PowerMax that allows you to migrate data between storage arrays without any downtime or disruption to host applications. During NDM, SRDF (Symmetrix Remote Data Facility) is used to replicate data between the source and target arrays. Here are the configuration rules that apply to SRDF groups and connections during NDM:

A. The source and target arrays are at most one hop away from the control host:The control host, which manages the NDM process, must have direct connectivity to both the source and target arrays. This ensures efficient communication and control during the migration.

E. DM RDF groups are configured with a minimum of one path:SRDF groups used for NDM (DM RDF groups) must have at least one active path between the source and target arrays. This ensures that data can be replicated continuously during the migration.

Why other options are incorrect:

B. Two DM RDF groups are created per SG migration session:This is not a strict requirement. The number of DM RDF groups may vary depending on the configuration and the specific NDM operation.

C. RF and RE ports are supported, with RF ports being selected if both types are available:While RF and RE ports are supported for SRDF, there's no specific preference for RF ports during NDM. The choice of ports depends on the overall network configuration and availability.

D. A single array cannot have multiple DM RDF groups:An array can have multiple DM RDF groups if needed for different NDM operations or configurations.

Questions 19

What will prevent a LUN from being assigned to a second Storage Group?

Options:

Both Storage Groups have a service level assigned

A LUN can only be assigned to one Storage Group

Storage Groups are already participating in a Masking View

One of the Storage Groups is a child group

Questions 20
