I am using the the HighPoint RocketRaid 2302 PCI-e card
http://www.highpoint-tech.com/usa/rr2302.htm

I have used their cards successfully for several years.
This is the first eSATA card I've used.

Hotswapping has the following problem. Has anyone seen this problem, and found a solution?

Problem: When the command
Code:
camcontrol eject da2
is issued, and the eSATA is physically disconnected, and after
Code:
camcontrol rescan all
is run, the command
Code:
camcontrol devlist
still shows the disk

Here is an example of an eSATA (da2) being successfully recognized, when it is attached:
Code:
tail -3 /var/log/messages
Jun 11 11:40:57 potter34 kernel: hptrr: start channel [0,0]
Jun 11 11:40:57 potter34 kernel: hptrr: [0 0] Start channel soft reset.
Jun 11 11:40:57 potter34 kernel: hptrr: channel [0,0] started successfully

And, for completeness sake, the following command
Code:
camcontrol reset 0:2:0
or
Code:
camcontrol reset 0:2:0
camcontrol rescan all
does not fix the problem, that is
Code:
camcontrol devlist
still 'sees' the disk that is not there.

I had thought of that, but this disk is seen as a SCSI disk, not as an ATA disk, so it turns out that
Code:
atacontrol list
doesn't even see the disk. This is confirmed by the man page.
Thanks though, for the suggestion.

Can you try:

Code:
camcontrol reset 0
camcontrol rescan 0
?

Code:
camcontrol reset 0
never returns to the prompt. And, in the process table you see this
Code:
root        1449  0.0  0.0  6052  1120  v0  D+   10:06AM   0:00.00 camcontrol reset 0
Which means, as you know
Code:
D       Marks a process in disk (or other short term, uninter‐ruptible) wait
hmmm ... in uninterruptible wait.

I can not simply, from another xterm
Code:
kill -9 1449
But, I can open another terminal and do
Code:
halt -p
I should also note that the following sequence where 'camcontrol reset 0:2:0' returns an error
And, in a moment I'm going to place a note about 'halt -p' off my first thread, about the alarm on the card going off, and it not powering off (later this evening)

Look at this sequence and the error
Code:
# camcontrol eject da2
Unit stopped successfully, Media ejected

# camcontrol reset 0:2:0
Reset of 0:2:0 returned error 0x6

# camcontrol rescan all
Re-scan of bus 0 was successful
Re-scan of bus 1 was successful
Re-scan of bus 2 was successful
Re-scan of bus 3 was successful
Re-scan of bus 4 was successful
Re-scan of bus 5 was successful

# camcontrol reset 0:2:0
Reset of 0:2:0 returned error 0x6

# camcontrol devlist

<PIONEER DVD-RW  DVR-218L 1.02>    at scbus1 target 0 lun 0 (pass2,cd0)
Argg, it's still there.

Also hptrr hangs at halt -p

Also, a relevent observation is that upon issuing
Code:
halt -p
all of the disks get sync'd properly, and then the following message appears on the console

Code:
hptrr: [0 1] Failed to perform channel hard reset
hptrr: [0,1,0] device is disconnected on channel
and then either the RocketRaid card starts, and continues to beep, or the system board beeps, I'm not sure which one. And then, I have to manually power it off. It reboots w/o error since the disks have been sync'd

This leads me to believe that when the command
Code:
camcontrol eject da2
somehow the hptrr driver is not 'letting go' of the device.
Or, perhaps the RocketRaid card can not 'let go', and so this never gets back to the hptrr driver.

I will ask the contact in the man page for hptrr to look at this, and maybe HighPoint to take a look at this.

Solved - HighPoint supplied 2 packages

This has been fixed.
I ask http://www.highpoint-tech.com to take a look at this thread.

And after some discussion w/ them, they sent two packages,

hptraidconf-3.4-1.tbz
hptsvr-3.13-6.tbz

and a Readme and a pdf.

These packages provided a cli tool (I believe they also have a gui, and a web version) that allows me to 'unplug' the eSATA.

There is a lot of other functionality, e.g. creating raid arrays, with these packages, but I am only using them to 'unplug' the eSATA.

Together with their command line interface, and camcontrol I was able to cleanly unplug the eSATA. It is also useful, of course to watch /var/log/messages at every step of the way.

Here's an example of plugging in and unplugging an eSATA
I've intermixed their command line tool with the OS commands, in the order I ran them.

Watch da2 (WDC WD10EALS-00Z8A0) apppear, and then disappear. I will not post /var/log/messages, but it showed no errors.

The eSATA was first powered on (AC), then plugged into the eSATA connection. Then the following commands were run.

Code:
HighPoint CLI>query devices
ID      Capacity    MaxFree     Flag    Status    ModelNumber
-------------------------------------------------------------------------------
1/3     1000.20     0           SINGLE  LEGACY    ST31000528AS

After this sequence of commands, the eSATA was unplugged from the eSATA connection, and then powered down, in that order.

Thanks everyone for help thinking through this
