An apparatus comprises at least one processing device configured to determine a set of one or more log patterns to utilize for scanning a set of logs associated with one or more information technology assets, a given one of the log patterns comprising a mapping between (i) at least a portion of a given raw log entry and (ii) a given descriptive textual label representing content of the given raw log entry. The at least one processing device is also configured to scan the set of logs associated with the one or more information technology assets to identify instances of the determined set of log patterns, to generate a log timeline of the identified instances of the determined set of log patterns, and to utilize the generated log timeline to cross-correlate the identified instances of the determined set of log patterns for the one or more information technology assets.

Cross-correlation of log patterns across information technology assets based on log timeline generation

A technique for managing data storage for virtual machines in a data storage system includes receiving, from a virtual machine administrative program, a request to operate a virtual machine disk (VMD) at a different service level from one at which the data storage system is currently operating the VMD. In response to receiving the request, the data storage system migrates the VMD from a first set of storage extents providing a first service level to a second set of storage extents providing a second service level.

Managing data storage migration for virtual machines

Techniques are described for copying data. At a first storage processor, a copy request is received to copy data including copying source data from a source area of a source logical device to a destination area of a destination logical device. The source logical device is owned by the first storage processor and the destination logical device is owned by a second storage processor. The first storage processor receives, from the second storage processor, destination location physical storage mapping information for the destination area. A destination physical device location corresponding to the destination area is determined. The source data from the source area is stored in a first cache location of a first data cache of the first storage processor. The first cache location is modified to indicate it includes write pending data for the destination physical device location. The source data is destaged to the destination physical device location.
