Subject: [PATCH 0/6] SCSI 'access_state' attribute
Date: Tue, 1 Mar 2016 05:55:37 +0100 [thread overview]
Message-ID: <1456808143-88932-1-git-send-email-hare@suse.de> (raw)
Hi all,
here's the patchset to add an 'access_state' and 'preferred_path'
attribute. It will display the access state of a path if a
hardware handler is attached.
The access_state is given in terms of SCSI ALUA, and
the vendor-specific access state (eg for rdac or alua)
are mapped onto the ALUA values.
Additionally the 'is_visible' callback is updated to
only display the attributes if they are supported.
Hannes Reinecke (6):
scsi: Add 'access_state' and 'preferred_path' attribute
scsi_dh_alua: use common definitions for ALUA state
scsi_dh_alua: update 'access_state' field
scsi_dh_rdac: update 'access_state' field
scsi_dh_emc: update 'access_state' field
scsi_sysfs: call 'device_add' after attaching device handler
