[PATCH 3/3] libata: don't start disks on resume

Disks with Power Up In Standby enabled that required the SET FEATURES command to start up were being issued the command during resume. Suppress this until the disk is actually accessed. --- drivers/ata/libata-core.c | 10 +++--- drivers/ata/libata-eh.c | 11 +++ drivers/ata/libata.h

[PATCH 1/3] sd: don't bother spinning up disks on resume

2013-11-06 Thread Phillip Susi
Don't bother forcing disks to spin up on resume, as they will do so automatically when accessed, and forcing them to spin up slows down the resume. Add a second bit to the manage_start_stop flag to restore the previous behavior. --- drivers/scsi/sd.c | 6 +++--- include/scsi/scsi_device.

Question on SCSI target scan

2013-11-06 Thread Ramesh Chikkanayakanahally
Hi, This question is related to scsi_transport_fc layer. Background:     When new LUNs are added to a target, the target can send check condition with SK/ASC/ASCQ indicating that the reported LUNS data has changed. Then the initiator can send the report LUNs command to discover the changes. But
