Subject: SATA hotplug from the user side ?
Date: Fri, 12 Jan 2007 08:57:09 +0100	[thread overview]
Message-ID: <1168588629.5403.7.camel@localhost> (raw)

Dear all,

I'd like to try out SATA hotplugging using a SIL3114. Though I was
harvesting the web, I could not find any useful information how this is
done in practice.

Well I realized that I can still use scsiadd to print and remove
devices, e.g.:

# scsiadd -p

Attached devices:
Host: scsi2 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: ST3400832AS      Rev: 3.01
  Type:   Direct-Access                    ANSI SCSI revision: 05
Host: scsi3 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: ST3400620AS      Rev: 3.AA
  Type:   Direct-Access                    ANSI SCSI revision: 05

# scsiadd -r 3 0 0 0

Is this all one has to do for hotplugging ? I am asking as I find this
in dmesg when I do so (2.6.19.* kernel):
