Configuration of new DS2100

[Victor_101]

I have just connected a DS2300 to a 4 port SCSI card on my rp2470 running HP-UX 11iv1. The output for ioscan -fn is
ba 3 0/4/0/0 PCItoPCI CLAIMED BUS_NEXUS PCItoPCI Bridge
i2o 0 0/4/0/1 iop_drv CLAIMED INTERFACE IOP
ext_bus 4 0/4/0/1.0 bs_osm CLAIMED INTERFACE I2O Block Stora
ge
target 6 0/4/0/1.0.0 tgt CLAIMED DEVICE
disk 3 0/4/0/1.0.0.0 sdisk CLAIMED DEVICE I2O RAID5
/dev/dsk/c4t0d0 /dev/rdsk/c4t0d0
target 7 0/4/0/1.0.7 tgt CLAIMED DEVICE
ctl 4 0/4/0/1.0.7.0 sctl CLAIMED DEVICE Initiator
/dev/rscsi/c4t7d0
ba 4 0/6 lba CLAIMED BUS_NEXUS Local PCI Bus A
dapter (782)


i cannot see this device in the ioscan -fnC disk
i have the default config and dip switches set to SES to support my OS. it is on a single bus mode and i have 4 146GB drives in the DS2300.

I also have a DS2100 connected on the same 4 port scsi card that has been working fine always as you can see from the above output. I tried a insf -e to install the special files but to no avail. I did not reboot once it all came up.. do i need to ? what do i need to do to make it available in the ioscan so that i can start using that space?

Reboot.

reboot didnt fix it. should i post this somewhere else ? reminder that the DS2100 and DS2300 are connected on the same 4 port SCSI adapter. and the DS2100 is on A and the DS2300 is on default dip switch setting.
any more ideas ? in general i would just need to run insf -e to install the necessary special files and it should detect right. is there a hardware issue?
the whole setup is brand new. the DS2100 is running since 6 months now.
after running the insf do i need to rebuild the kernel ??

Hi,

Pls remind that by default the initiator SCSI ID is 7 in DS2100 class devices. Maybe a SCSI ID's conflict is happening among them. In this case you must select a new SCSI ID that not be in use by other initiators and/or disks (check A,B,C rear switch setting). For more info pls refer at your producto user's guide.

The default initiator SCSI ID's can be changed by PDC interaction when interrupt the 10 awaiting seconds in the boot secuence.

When Main Menu is displayed select "SERvice menu" at the command line. Then, with the SCSI INIT command executio you can change the default SCSI ID at new at hardware.

To exit enter RESET at the command line. The system will be rebooted.

Also pls check in your syslog.log file if any message like this are logged:
ext_bus (vmunix: SCSI: Resetting SCSI -- lbolt: 412184, bus: n path: )

This message is a good hint to validate my theory.

Rgds.

Hi,
No, you don't need to rebuild the kernel after running insf command.
I agree with Mosquera that you should check the SCSI ID in both DS2100 and DS2300 first. Or you may temporary disconnect the DS2100 and see whether the system can detect the DS2300.
Good luck.

Hi guys ,
I fixed it. I remember i had a similar situation before. I needed to use IRM to configure the new devices on the new raid channel . Basically HBA configuration. All is fine. Thanks guys for the efforts.
