An administrator receives notification that the vxconfidd daemon has stopped on a Veritas InfoScale Storage production server that has been running applications on mounted Veritas file systems. What is the impact of this failure?
application I/O fails; all Veritas file systems are disabled
application I/O fails; all imported disk groups are disabled
application I/O continues; I/O performance to disk is degraded
application I/O continues; VxVM configuration changes fail
An administrator has configured replication using Veritas Volume Replicator between two sites. The replication mode is set to asynchronous and the replication status is consistent and connected. The performance of which component impacts the application write performance?
write performance of the primary SRL volume
write performance of the secondary SRL volume
write performance of the data volumes at the primary site
network latency between the primary and the secondary sites
Which command attempts to repair a missing disk access records by finding the name of the device in the private region and matching it to an existing disk media record?
vxmend
vxdctl
vxreattach
vxrecover
What is the advantage of making storage checkpoints automatically accessible through a directory named .checkpoint in the root of the file system?
it ensures a storage checkpoint is automatically deleted under certain conditions
it eliminates the need for manually mounting storage checkpoints
it ensures the inode number of a file is different across storage checkpoints
it automatically creates a new storage checkpoint as changes are made to the file system
