Reset pci card HPUX 11.11 rp2470

[G. Vrijhoeven]

Hi,

We have problems with a scsi bus and lost a tape drive that is connected on the bus. I like to try to reset the scsi bus. But i can not find the commands to do so.
I know of the frupower command, but this is not supported on this hardware.
prc03b11:/ #frupower -d
Error: Unsupported platform. Command aborted. (-12)

Is this possible to do remote since the server is in a datacenter 70 KM away.

Hope so can help me.

Thanks in advance.

Hi,

is your card OLAR-able ?
(sam --> Peripheral Devices --> cards)
I dont think so but I dont have a rp2470 to verify.

Do you have a remote console connection? If so you can go there, get to the maintenace processor (cntl-B) and looks at error logs.

Other ideas:
- reboot
- install latest SCSI driver patch

Hi Gideon,

You can only power off and on the card (at your risk). For that, the card should support OLAR. You can use 'rad' command do it if the card is OLAR'able. 'man rad' for more details.

There isn't anyway to reset the SCSI bus. You will need to reboot the box so that diagnostics are run on the IO.

Thanks for the replies.

I will try your anwers and assign points in the morning.

The tape drive and the dvdrom drive are external and hot swappable, so an operator switched the devices and now we are able to see them both again.

I have no experience with OLAR yet and i think changes are the device does not support OLAR since it is onboard scsi controller in a SPOF box. Will try it on a rp7410 as well, just to see if it works.

Thanks again, and regards,

Gideon

You are correct, the rp2470 server does not have OLAR support (but the rp7410 does).

Also, the suggestions about looking into the cause of the error are good, because there really shouldn't be any reason you have to reset the SCSI bus.

With that said, it is possible. See scsictl(1M).
