| Subject: [SCSI] mpt2sas: Fix device removal handshake for zoned devices |
| |
| From: Kashyap, Desai <kashyap.desai@lsi.com> |
| |
| commit 4dc2757a2e9a9d1f2faee4fc6119276fc0061c16 upstream. |
| |
| When zoning end devices, the driver is not sending device |
| removal handshake alogrithm to firmware. This results in controller |
| firmware not sending sas topology add events the next time the device is |
| added. The fix is the driver should be doing the device removal handshake |
| even though the PHYSTATUS_VACANT bit is set in the PhyStatus of the |
| event data. The current design is avoiding the handshake when the |
| VACANT bit is set in the phy status. |
