You create a new Symmetrix VMAX volume to be used as a VMFS store for a new ESX host. You map the volume to two FA ports already being used by Windows hosts. After rescanning the bus, the new ESX host is unable to discover the volume. You identify that the SCSI-3 and SPC-2 flags need to be enabled for the

ESX hosts.

What should you do to resolve this issue?

What are the slices on the physical disks in a Symmetrix called?

Click on the calculator icon in the upper left. A customer requested assistance in using the symcli symconfigure command to create one 8-way 1 TB striped meta bound to POOL_A.

Which parameters do you provide?

A Symmetrix VMAX 40K customer uses TimeFinder/Clone to replicate their production database. The Symmetrix devices used by the database are under the control of XtremSW CachE.
-- An issue with the production database requires a recovery from the TimeFinder/Clone replica. --
Production was stopped in an orderly manner and the production file systems were unmounted.
-- A TimeFinder/Clone restore was attempted with the default options.
-- The restore fails.

Why did the restore fail and what should be done for a successful restore?

What is the sequence of operations for completing an Open Replicator data copy?

How many mirror positions does a RAID 6 protected volume occupy in a Symmetrix running 5874 Enginuity?

What happens when a Snap session is terminated?

Multiple RDF groups from different Symmetrix arrays have been grouped together to enable Multi-Session Consistency.

How does cycle switching occur in this configuration?

What is the purpose of a DX port on a VMAX array?

A customer is using Virtual Provisioning on a Symmetrix V-Max array. A thin pool has been created and ten (10) 10 GB data devices have been added and enabled. The "Maximum Subscription Percent" has been set to 300.

How many 10 GB thin devices can be bound to the thin pool?

After creating and then activating a clone session, which process is used to satisfy a read request to the clone target for a protected track?

A customer currently manages their Symmetrix V-Max array environment with SYMCLI within the administrative storage group. They are instituting a third-shift operations group that will perform storage tasks such as device creation, device mapping, and LUN masking.

What solution fits this expanding business requirement and organizational change?

A storage administrator failed to monitor the available capacity in the SAVE pool.

What happens on the next write to a full pool?

A VMAX administrator has excess capacity in a Snap pool.

How can this excess space be reallocated to other enabled devices in the same Snap pool?

What could be a reason for a TimeFinder/Snap session to be placed in a failed state?

When is Virtual LUN migration supported on a Symmetrix V-Max array?

The precopy option (-precopy) was specified when creating a TimeFinder/Clone session.

What occurs after the background copy of the source to the target completes?

You need to perform an SRDF failback operation and must ensure the integrity of the data on the R2 volume.

Which step must be taken?

How can you mount a TimeFinder replica on an ESXi host, when the R2 device is also seen by the same host?

An SRDF/A session is active and the device pairs are in a consistent state.

What will happen if there is a temporary loss of all links?

How is data read from a compressed track on a Symmetrix thin device?

A customer needs to replace an HBA on an existing host connected to their Symmetrix VMAX array and is unsure how to update the host masking to reflect the new HBA WWN.

What is the most efficient way to complete the host masking update?

The customer is considering a long-distance replication solution. Due to bandwidth limitations and distance SRDF/A has been selected. The customer has called the EMC TA to review his RPO.

With a customer-selected minimum cycle time of 30 seconds, what is the worst-case RPO under normal operating conditions?

What is a benefit of using TimeFinder VP Snap instead of TimeFinder/Clone when running Enginuity 5876 onward?

Which Unisphere for VMAX view shows all the components of a masking view including the members of the various groups (port, storage and initiator)?

A Symmetrix VMAX customer created five thin devices and added them to a storage group. The storage group is part of a masking view for an HP-UX Server. The administrator scans for the five new devices and sees that the devices are Not Ready.

What is the reason for this?

Refer to the exhibit.

An Oracle database server has its logs and data split between two Symmetrix V-Max arrays at the primary site. Synchronous consistency protection was enabled for the log and the data devices.

What will occur if the link between the Symmetrix V-Max array containing the log LUNs and the target Symmetrix V-Max array were to fail?

Refer to the exhibit.

What is the correct state for the Target R2 and Target BCV prior to issuing a symreplicate start command?

A customer's environment consists of several servers that require the presence of LUN #0 to function properly.

What is the optimal way of attaching these servers to a Symmetrix V-Max array?

How many mirror positions does a RAID 1 protected volume occupy in a Symmetrix running 5874 Enginuity?

Refer to the exhibit.

What are the prerequisites for using the symclone recreate command on a Symmetrix V-Max array?

When creating a new Symmetrix logical volume with SYMCLI, what unit can be used to specify the size?

What is a requirement for implementing SRDF in a Virtual Provisioning environment?

A TimeFinder VP Snap session has been created and activated at 10 AM. Subsequently track number 1000 is written to on the Source device. At 11 AM a second TimeFinder VP Snap session is created and activated for the same Source device. After activation of the second session track number 2000 is written to on the Source device.

How will a read request to track 2000 on the target of the second TimeFinder VP Snap session be serviced?

How does Transmit Idle help in an SRDF/A deployment?

What happens when all the thin devices are unbound from a thin pool?
