greetings all: i have a couple of questions i hope someone can answer for me.
to start: i have a sparc station and linux (debian 2.1, 2.0.35 kernel) 1st question - re: scsi my system works pretty good. i am only curious as to why the sparc scsi bus locates the internal system hard drive as target 3 when i have external hard drives, as it is physically closer to the system. i.e. esp0: FAST chip is fas100a (family=0, version=2) ESP: Total of 1 ESP hosts found, 1 actually in use. scsi0 : Sparc ESP100A-FAST scsi : 1 host. Vendor: SEAGATE Model: ST15230N Rev: 0638 Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sda at scsi0, channel 0, id 0, lun 0 Vendor: SEAGATE Model: ST15230N Rev: 0638 Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sdb at scsi0, channel 0, id 2, lun 0 Vendor: SEAGATE Model: ST1480 SUN0424 Rev: 8628 Type: Direct-Access ANSI SCSI revision: 02 Detected scsi disk sdc at scsi0, channel 0, id 3, lun 0 Vendor: HP Model: C1533A Rev: 9503 Type: Sequential-Access ANSI SCSI revision: 02 scsi : detected 3 SCSI disks total. sda and sdb are in an external box (scsi id 2) whereas the small internal is sdc. i am just curious why the sparc does not find and id the internal first, i.e. target 0 or 1; sda. ??? 2nd question: re: tape backups. i am trying to finess mt, dump, and restore to do the job for us. they work o.k., except that there are a few main information bits that seem to be missing. i went through the mans on each of these, and i can't see anywhere an operation that will tell me how much space is left on the tape. GNU mt version 2.4.2 Package: dump Version: 0.4b4-13 3rd question: cdrom drive: i also have a cdrom drive ii want to put on the system. whenever i add it to the chain, however, i get a scsi bus interrupt; reset infinite loop when i try to boot. here's how my system looks as above for the hard drives. external case with hard drives: id 2 plus: hp tape backup: scsi id 4 this configuration works fine. but when i add the cdrom to the end of the chain, i have the problem. the last device is terminated properly. with respect to scsi types; sparc - (fast scsi 2) --> external drives (scsi) --> hp tape (scsi) --> cdrom (sun - fast scsi 2) i tried setting the cdrom as device 5 and 6, neither worked. however, the nvram probe-scsi util did find them all properly and it looked fine in that setting. it was only when i went to boot when it went into an infinite loop. could it be a driver problem? i have the sg and st modules loaded. thanks for any assistance with this. bill
