Read_efi_hdr: physio failed

Rubin Simons — Tue, 19 Jun 2007 08:50:34 GMT

Hi all,

On a rx8640 running HP-UX 11.23 we are seeing some weird messages pop up in dmesg. These messages happen when we do an 'ioscan -fn && insf -e', which incidentally takes much longer than normal (2 hours).

The message is:

read_efi_hdr: physio failed

We started looking at dmesg because the scan took so much longer than usual; it might be unrelated.

Also (and again maybe completely unrelated) idisk coredumps when trying to verify volumes on the SAN. Is that normal behaviour? I could imagine this not working however the coredump worries me a little:

# idisk -v /dev/rdsk/c24t8d5
Floating exception(coredump)

Hi Rubin,

Explaination for : read_efi_hdr: physio failed is..

Command "ioscan -e" which display the EFI device path when available.

This commands leaves the devices partially open. Accessing a disk in this state will result in the syslog message.

This is a known issue and fixed with Patch: PHKL_33432 superseeded by PHKL_34588

Now about Floating exception(coredump).. in one of my case installing the FSLibEnh patch resolved the issue..

FSLibEnh B.11.23.07 libc enhancemnts for VxFS4.1 and 5.0

from Sep 2006 media
