Hi,
I would like to hotswap hard disks (for backups) with a Promise PDC40518
SATA150 (a.k.a. S-ATA II 150 TX4). Both SATA hard disks on this
controller are found while booting. I can mount and use the drives. And
this works very nicely and fast.
But if I detach a drive via atacontrol or via the SATA hotplug-able
backplane then the drive is gone and cannot be re-attached anymore.
# atacontrol list
[...]
ATA channel 5:
Master: ad10 <WDC WD2000JD-98HBB0/08.02D08> Serial ATA v1.0
Slave: no device present
# atacontrol detach 5
# atacontrol attach 5
Master: no device present
Slave: no device present
Then I find the following messages in the log:
for detaching:
kernel: ad10: WARNING - removed from configuration
for attaching:
kernel: ata5-master: timeout sending command=ef
kernel: ata5-master: error issueing SETFEATURES SET TRANSFER MODE
command
kernel: ata5-master: FAILURE - ATA_IDENTIFY timed out
kernel: ata5-master: timeout sending command=ec
kernel: ata5-master: error issueing ATA_IDENTIFY command
Interestingly, in the booting process detection works fine (FreeBSD-5.4-
Release #0 with the generic kernel):
kernel: atapci1: <Promise PDC40518 SATA150 controller> port
0xb000-0xb0ff,0xb400-0xb47f mem

Exists there a patch or a workaround for this problem?
Thanks!
Best regards,
David
