ioscan NO_HW but disks visible & usable
When I run ioscan, all external disks show up as NO_HW however we can see and use the disks with no apparent issues. However, when I try to assign additional storage to the server, the new disks do not show up in the ioscan list.
I know there was a patch for ioscan running under 11.11 to fix a similar issue with disk paths starting with 255 (which these ones do), but cannot find a similar patch for 11.23
Any advice on this one would be appreciated.
Thanks, Adriaan

Re: ioscan NO_HW but disks visible & usable
What happends if you do a pvdisplay in one of those disks that show up like that?
Have you run vgchange at some point, and have you made some recent changes?

Re: ioscan NO_HW but disks visible & usable
and check that you are seeing new devices. NO_HW devices might be old device files and not usable since something is changed like removed from LVM.

Re: ioscan NO_HW but disks visible & usable
Looking at the ioscan again, we seem to have the same issue with the DVD rom and the rereporting problem with the disks appears to start with the iscsi card.

Re: ioscan NO_HW but disks visible & usable
You do seem to have an anamoly here.
Controller 4 shows NO-HW yet the disks are good.
I think the problem with the controller will eventually cause disk problems so have hardware replace the controller and be done with it.
