Storage device to provide access to storage resources over a data storage fabric

摘要

Provide access to storage resources of a storage device over a data storage fabric. Allow a zone manager of a first switch to assign a zone group to one of a plurality of phys of an expander of the storage device to allow the first switch to access storage resources of the storage device. If status of the phy that is assigned a zone group indicates a disconnection condition with the first switch, then configure the zone group of the expander of the storage device to prevent access to the storage resources of the storage device. If after the disconnection condition, the status of the phy indicates a reconnection condition with a second switch, then allow a zone manager of the second switch to assign a zone group to the phy to allow the second switch to access storage resources of the storage device.

1. A storage device to provide access to storage resources over a data storage fabric comprising:
an expander having phys (physical layers) to be assigned zone groups to enable access to storage resources of the storage device over a data storage fabric; and a storage manager to: enable a zone manager of a first switch to assign a zone group to one of the phys of the expander of the storage device to enable the first switch to access storage resources of the storage device, determine when status of the phy that is assigned a zone group indicates a disconnection condition with the first switch, then configure the zone group of the expander of the storage device to prevent access to the storage resources of the storage device, and determine when after the disconnection condition, the status of the phy indicates a reconnection condition with a second switch, then enable a zone manager of the second switch to assign a zone group to the phy to enable the second switch to access storage resources of the storage device.
