An SRDF failover has been executed during the testing phase of an implementation. What is the expected status of the R1 and R2 devices after performing SRDF failover operation?
R1 Wnte Disabled; R2 Read/Wnte
How does TimeFinder emulation mode convert commands?
Snap commands are converted to Mirror commands
Which of these protection types offers the best protection?
RAID 5 (3+1)
What is the maximum volume size configurable on a V-Max?
You have been asked to create a configuration for a single engine Symmetric V-Max array with 8 DAEs and 64 drivers. They would like to have the data devices with RAID 5(7+1) protection. What would be the largest number of members you would recommend for a stripped metavolume?
A customer using Symmetrix Virtual Provisioning reports their thin pool has reached 50% utilization. At which utilization level would you recommend adding more capacity to the thin pool?
What is another possible scheme for RAID 6 for a Symmetric V-max besides 6+2?
Which feature allows the contents of a BCV to remain unchanged during and after operation? Even while the BCV and the standard is synchronized?
An SRDF/A session is active with Transmit Idle enabled. The device pairs are in a consistent state. What will happen if there is a temporary loss of all links?
RPO will increase
Open Replicator will be used to move data from a Symmetrix V-max array to a CLARiiON array. The CLARiiON array has NOT been discovered by the host on which Open Replicator commands are issued. Which information has to be specified in the Open Replicator device File?
symdev=arrayed:device www=CLARiiON device WWN
What is a requirement for implementing SRDF in a Virtual Provisioning environment?
Source device is thin, target device is thin.
In a single hop SRDF/AR setup the options have been set as follows Cycle time-300 Delay Time-200 Overflow: Next The symreplicate session was started at time 0. The actual cycle was 450 seconds. How many seconds after the start of first cycle will the next cycle start?
Under which condition will Enquiry remove the Consistency Exempt attribute from the RDF mirror?
Deleting RDF pairs
Open Replicator will be used to move data from a Symmetrix V-Max array to a CLARiiON array. The CLARiiON has NOT been discovered by the host on which the Open Replicator commands are issued. Which information has to be specified in the Open Replicator device file?
The WWN of the CLARiiON LUN
How do you examine the attributes of a Dynamic SRDF device?
How many SRDF groups can a Symmetrix VMAX array support?
Which two TimeFinder/Clone actions are initiated when issuing a Symclone establish command?

Multiple RDF groups from Different Symmetric arrays have been grouped together to enable Multi Sessions consistency. How does Cycle Switching occur in this configuration?
Cycle switches are controlled by RDF daemon
What is recommended before creating a TimeFinder/Clone replica?
Ensure that the clone target devices are not being actively accessed
What is required to ensure the integrity of data on the R2 volume during a SRDF fallback operation?
Stop any applications that are accessing the R2 volume
