Patent ID: 8868870

Claim:
A computer-implemented method for managing off-host storage migration, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: detecting an action to perform non-disruptive data migration from an existing off-host storage array to a new off-host storage array by: 1) identifying a new communication path that is established in a manner that a host system perceives the new communication path as a path from the host system to the existing off-host storage array, 2) determining whether the new communication path comprises a standby path that is not actively being used for communication between the host system and the existing off-host storage array, 3) when the new communication path is determined to comprise the standby path, determining whether the new communication path actually comprises a path to the new off-host storage array configured in a manner that the host system perceives the new off-host storage array as the existing off-host storage array by performing at least one of: using an inband Small Computer System Interface (SCSI) inquiry command to determine that the new off-host storage array is different than the existing off-host storage array; using an out-of-band array management interface to determine that the new communication path is from a different physical storage array than the existing off-host storage array; detecting that a communication channel transport identifier for the new communication path does not belong to the existing off-host storage array, 4) when the new communication path is determined to comprise the path to the new off-host storage array, concluding that the non-disruptive data migration is being performed; performing at least one management operation with respect to the new off-host storage array.
