Subject: [ANNOUNCE] sdparm 1.12 available
Date: Fri, 23 Apr 2021 12:56:35 -0400	[thread overview]
Message-ID: <af2547f1-33af-fa26-3242-17a60b331b86@interlog.com> (raw)

sdparm is a command line utility designed to get and set SCSI device
parameters (cf hdparm for ATA disks). The parameters are held in
mode pages. Apart from SCSI devices (e.g. disks, tapes and enclosures)
sdparm can be used on any device that uses a SCSI command set. sdparm
also can decode VPD pages including the device identification page.
Commands to start and stop the media; load and unload removable media
and some other housekeeping functions are supported. sdparm supports
the Linux kernel 2.6, 3, 4 and 5 series with ports to FreeBSD, Solaris,
Android and Windows.

ChangeLog for released sdparm-1.12 [20210421] [svn: r347]
   - add Command duration limits T2A and T2B mpages
   - add Sequestered command fields in Control extension mpage
   - SAS/SPL disconnect-reconnect mpage: BILUNIT and CTLUNIT
     fields added (21-021r3)

   - add SAT ATA Feature control mpage (20-085r4)
   - block device char vpd page: add zoned strings
   - expand Out of band management control mpage (spl5r08)
   - vpd: add Format presets and Concurrent positioning
     ranges pages
   - vpd: standard inquiry: add hot_pluggable field
   - sg_lib: allows access to cache mpage's WCE for nvme

ChangeLog for sdparm-1.11 [20200303] [svn: r334]
...


An experimental feature noted in the ChangeLog is the ability
to set and clear WCE (write cache enable) on a NVMe disk. More
NVMe support may creep in on a as needed basis in the future.
And 'sdparm -i <nvme_ns>' will output NVMe device identification
data formatted in the same fashion as the SCSI Device
Identification VPD page.
