Subject: sysfs method for registering/unregistering ide devices ?
Date: Sat, 13 Mar 2004 16:43:57 +0200 [thread overview]
Message-ID: <1079189037.6624.11.camel@t40> (raw)
Hello,
Is there any possibility to unregister/scan ide devices with sysfs ?
I've searched lkml and linux-ide list archives and I didn't found any
answers.
Is there any sysfs file like /sys/..../registered, where you could echo
0 or 1 if you want to register or unregister a specific interface ?
Till now, I used hdparm -U/-R option for this task.
While this is still available in kernel 2.6, the implementation of
HDIO_UNREGISTER_HWIF and HDIO_SCAN_HWIF seems more like a hack than a
sane implementation.
Reasons:
Unregister and then register the same device, and you will have
different files for it int procfs and sysfs.
For unregistering or registering a device, you need at least a valid
block device. So I cannot unregister all my drives, and register them
again (or at least not at the same time).
