Hello,
could you please help us with the following: we have IFT controller, which
allows us to create several (up to 64) logical units, which are routed to
scsi channels with one (different for each channel, though) id and different
lun's.
There are no problems when you create two logical units and each of them is connected to different channel (hence, different id's). Both channels are connected
to one scsi bus as different devices:
term---+----+---------2940uw
| |
id1 id2
sd0 at scbus0 target 1 lun 0
sd0: <IFT 3102 0112> type 0 fixed SCSI 2
sd0: Direct-Access 8683MB (17783104 512 byte sectors)
sd1 at scbus0 target 2 lun 0
sd1: <IFT 3102 0112> type 0 fixed SCSI 2
sd1: Direct-Access 8683MB (17783104 512 byte sectors)
In case the same devices are connected to the same channel (hence, getting
the same id with different lun's) -
sd0 at scbus0 target 1 lun 0
sd0: <IFT 3102 0112> type 0 fixed SCSI 2
sd0: Direct-Access 8683MB (17783104 512 byte sectors)
sd1 at scbus0 target 1 lun 1
sd1: <IFT 3102 0112> type 0 fixed SCSI 2
sd1: Direct-Access 8683MB (17783104 512 byte sectors)
While working with separate device everything goes ok then; when you ccd those,
errors like the below described start to appear:
sd1: SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0
SEQADDR = 0x8 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa
sd1: SCB 0: Immediate reset. Flags = 0x1
sd1: no longer in timeout
ahc0: Issued Channel A Bus Reset. 2 SCBs aborted
sd1: UNIT ATTENTION asc:29,0
sd1: Power on, reset, or bus device reset occurred
, retries:3
What we think here: it's hardly IFT's (i.e. hardware problem), it can work with
different lun's (we checked on two different IFT devices), it's neither
aic7880's trouble (it works with several lun's, doesn't it?), - might be some
error in ahc driver. Likely, it isn't a typical case when fast devices like sd
get one id and different lun's and isn't tested ok. This situation is the
very same for -stable as well as for -current.
