<0> b1ackcat: check your permissions on the device
<1> if I connect scsi2 hdds along with u160 devices on the same controller.. will it affect the performance of the u160 devices?
<2> if on the same bus, then hell yes
<2> if you put ANYTHING that isn't LVD on a lvd bus, the whole bus will degrade to 40MB/s max
<1> I see, thanks
<3> yeah, scsi channels generally get nerfed according to the lowest speed device
<3> but why would you even **** around, you can get scsi-2 controllers for free
<1> more cards doesn't solve irq problems
<1> the performance will degrade overall, if I add more cards
<1> better yet, I don't add those scsi2 devices at all ;P
<3> good scsi controllers don't cause huge loads from interrupts, and scsi-2 doesn't exactly contribute to the saturation of a pci bus
<1> I have an adaptec 19160, the documentation only warns about connecting non-u160 to the LVD/SE connector
<1> it also has 50pin connectors for fast/ultra
<1> does that mean they're not on the same physical bus?
<2> yes and no...
<2> ahem
<1> http://www.adaptec.com/en-US/support/scsi/u160/ASC-19160/_docs/19160_users_reference_pdf.htm
<2> there is a so called "isolation" between these to "bus halves"
<2> so put the slower devices on that 50pin connector
<4> *swears loudly at isp*

<4> you must have different scsi id for all the things though
<1> digix_: so, you come to the same conclusion as me
<4> you must have different scsi id for all the things though
<1> but it must also mean that at any time, the fast/ultra device will be blocking the u160 devices for 8x as long
<4> hm..yeah..kinda
<4> make sure you have "bus disconnects" supported on everything
<1> what's that?
<1> so that a disconnect doesn't reset all devices?
<4> with bus disconnects, a scsi bus is kinda ..um.. multitasking...
<4> scsi card sends a command to one device, then that device can "disconnect" from the bus,
<4> so the card doesn't have to wait for it to reply before sending a command to some other device
<1> I had a problem (that I never bothered to solve) with multiple scsi cd-r, when one of them finished recording, the bus would reset halting all of the recorders =(
<1> ok, I see it's not related ;P
<1> digix_: is that a feature of each device, or only a card setting?
<4> both card and devices.
<2> argh
<2> I definetely have to look into switching isp
<1> heh
<2> both card and devices.
<2> this is the BIG differency between scsi and ide
<2> if you put two drives on an ide channel, only one device really operates at a time
<1> what if the device specs don't implicitly mention this? are they likely to support it?
<2> well..hmm... i think bus disconnects is a feature of scsi2 and upwards..
<2> most scsi2 hdd prolly supports it
<2> cdr's are perhaps a little less likely to support it...but most of the time they do too, i thinkl..
<1> I still have my old yamaha cdrs, probably the best cdrw drives ever made
<1> good for making cd masters..
<5> does slackware have any type of frontend for manageing what services start and stop?
<3> not really
<3> just set/unset the executable bit on the scripts
<3> a front end couldn't make it more simple
<5> resfilter, well wait, if you set the x bit to - for whichever script, wouldn't you get exec errors durring boot up?
<6> the script that calls the other scripts has an if... it checks permissions to see if those scripts should be run
<6> have a look at the scripts in /etc/rc.d/
<7> Life is good.
<8> mogi: you about?
<8> looking for a way to turn down the volume on thunderbird sounds
<8> apparently it takes the default alsamixer volume
<8> and we want it to not to
<9> morning
<10> morning.
<9> morning phyber
<11> when i'm in console and press tab i get that annoying beeping from the computer, how do I disable this?
<1> heh, I bought a 3.5mm stereo jack to repair a pair of headphones
<1> damn I like those headphones
