Abstract: During preparation for migration of a logical volume from a source data storage appliance to a destination data storage appliance, a determination is made as to whether at least one host that accesses a copy of the logical volume contained in the source data storage appliance is managed by a host administration server. In response to determining that at least one host that accesses the copy of the logical volume contained in the source data storage appliance is managed by the administration server, a rescan request is transmitted to the administration server. The rescan request causes the host administration server to instruct each host that is managed by the host administration server that accesses the copy of the logical volume contained in the source data storage appliance to perform a rescan operation to discover at least one new path to the logical volume.

Abstract: A method is used in managing multi-tiered storage pool provisioning. One or more physical devices of a data storage system are configured for use in connection with provisioning a storage pool. A provisioning specification is received describing a RAID type and an auto-tiering selection. A rule is received describing one or more sets of data storage system best practices. Each of the one or more sets specifies data storage system best practices for a different type of data storage system including a first type associated with the data storage system. Configuration processing is performed in connection with initialization of the data storage system to configure a first portion of the one or more physical devices for use with auto-tiering in the storage pool. A rules engine and best practices for the first type of data storage system specified in the rule are used in performing the configuration processing.
