Subject: [PATCH 0/3] hpsa compatility fixes
Date: Fri, 18 Nov 2016 08:32:46 +0100 [thread overview]
Message-ID: <1479454369-100281-1-git-send-email-hare@suse.de> (raw)
Hi all,
this is a patchset to get hpsa working on older controllers.
Most notably older controller do not support the extended REPORT PHYS
command, so we need to fallback to the legacy version here.
I've also added a new sysfs HBA attribute 'ctlr_num', which displays
the current controller number. With that attribute one can construct
legacy '/dev/ccissX' symlinks to facilitate an update from older
installations using the cciss driver.
As usual, comments and reviews are welcome.
Hannes Reinecke (3):
hpsa: use correct DID_NO_CONNECT hostbyte
hpsa: fallback to use legacy REPORT PHYS command
hpsa: add 'ctlr_num' sysfs attribute
