HP Unix Interview Questions and Answers part 4


Q: – Why is install.log so difficult to read?

 The installation messages that are logged into install.log are obtained by Ignite-UX from multiple sources including the standard output (stdout) and standard error (stderr of Software Distributor and the contents of swagent.log. It is not possible to control how these messages are logged into install.log, thus the file can be confusing.
If you want to verify the installation of a product, HP recommends that you examining the swagent.log file directly, rather than the Ignite-UX install.log file.

Q: – Why am I getting the following message? pax: Cannot access /sbin/pax_enh : No such file or directory.

 If you try archiving using pax format, you see the following message:
pax: Cannot access /sbin/pax_enh: No such file or directory
pax:  PAX-ENH product needs to be installed to enable the options -A, -o exclude and -o graph.
WARNING: The pax command returned a non-zero exit status (exit status 1).

You need to install PAX-ENH product to create pax format tape archives using make_tape_recovery, even on 11.31.

Q: – Why did it call my client "<hostname>.0x080009…."?

If your client has multiple LAN interfaces, and you have previously installed the client using one interface, and then later chose to use the other interface during the installation, then the client name will have the LLA (link-level address) appended to the host name so that it does not conflict with the prior host name left from the prior installation.

This may also happen if you had to replace the LAN interface in your client since the last time you installed it. The LLA number is attached to the LAN interface, not the client. It is only the name of the icon that has been renamed. You can use the Ignite-UX GUI "Action" menu to "Change icon name" to rename oneor both of the clients

Q: – How do I include all volume/disk groups into a recovery tape ?

To include all volume and disk groups on the system into a recovery tape (can be used with make_net_recovery as well) use the following command:
# make_tape_recovery -A -x inc_cross=/
The make_tape_recovery manual page defines inc_cross as follows:
-x inc_cross=file|dir
Includes the file or directory in the recovery archive and crosses mount points to access any directories that are mounted or files contained in directories that are mounted.

Q: – We tried running the recovery system option from a client booted inIgnite-UX, which generated errors. for tftp? What files need to be accessible for tftp?

Only /opt/ignite and /var/opt/ignite are needed for tftp access.

Q: – How do I deal with hot-swappable disk devices during recovery?

Ignite-UX only supports hot-swappable disks that are completely installed and present when creating a recovery image. Proper software and hardware procedures must be used for hot swap disk removal or replacement before or after recovery, but not during. The LVM command lvlnboot used by save_config does not work when a disk is removed and the system is in this transitional state. If this command is not working, then recovery has no chance of succeeding.

Q: – What is the maximum amount of data that a make_tape_recovery tape can hold?

 A make_tape_recovery tape can hold as much data as will fit on the tape. If make_tape_recovery is run in the foreground it prompts for more tapes if they are necessary.

Note that to include files larger than 2GB but less than 8GB you may need to install patches. On HP-UX 11.11 you must have PHCO_28414 or later installed. On HP-UX B.11.23 you should have PHCO_31634 or later installed. Otherwise files will be limited to being less than 4GB in size.
