Itanium error 55, uuid

[Tim Leong]

I just set this machine up out of the box. When I boot, I get:

Error[55] UUID error

Any idea what this means or how to fix it?

Hi Tim,

UUID is Universal Unique ID. Used by DCE & NCS - specifically by the lb (Location Broker).

Can also mean Unique User ID & telnetd would user it if started out of inetd with -t.

See if you can get up in single-user mode & check the telnet line in inetd.conf.
Also if you're not going to be running NCS daemons, then check the /etc/rc.config.d/ncs & set the start_llbd & start_glbd params to 0.

I believe that the SharedPrint/UX SW also uses the Location Broker.

HTH,
Jeff

Thanks for the reply Jeff.

I get this error before the hp-ux bootloader, so it doesn't seem like it would be any of the inetd services. I would be able to troubleshoot this further, but it's itanium and thus, very different. The only thing I'm able to use is the EFI shell. Would you know a way to resolve this through that shell?

Hi Tim,

Found this in case you're running RedHat on this Itanium.

Modifying /etc/fstab to Avoid Hangs with mount, umount, and fsck

RedHat installations by default use the label feature for specifying the mount device using the keyword LABEL= or UUID= in the /etc/fstab file. This usage can create hangs when running the mount, umount, and fsck commands, which are used in package control scripts. To see whether you are exposed to this hang problem, edit /etc/fstab and search for any lines starting with LABEL= or UUID=.

In the /etc/fstab file, the first field specifies the device that will be mounted at the mountpoint specified in the same entry. If your file contains entries in the first field that use the LABEL= or UUID= keywork, you need to change the entries to use actual device file names.

The following entry illustrates the problem:

LABEL=/xyz /xyz ext2 defaults 1 1In this case the entry "LABEL=/xyz" is used instead of a device file name, so you need to replace it with the actual device file name. Use the following procedure:

First, verify that the filesystem is already mounted at /xyz. You can do this using the following command:

# df | grep "xyz"

If the output shows a line like the following, then the file system is already mounted.
/dev/sda7 132207 14548 110833 12% /xyzIf this kind of line does not appear, you need to mount the file system, as in the following:

# mount /xyz

After mounting the filesystem, issue the "df | grep xyz" command again and this should give you the same output that was shown before:
/dev/sda7 132207 14548 110833 12% /xyzThe first field on this line is the device file name, in this case "/dev/sda7".

Replace "LABEL=/xyz" with "/dev/sda7" in /etc/fstab. The rest of the fields on the same line need not be touched.

Do the same for every such line in /etc/fstab that uses LABEL= or UUID= keywords.

Note that the system does not need to be rebooted after editing /etc/fstab.
Whenever you create file systems, check the /etc/fstab to make sure that the entries do not use labels. If they do, use the above procedure to change them.
