Notes That Are Common to Both Upgrade Types

Upgrade Does Not Require All Patches For Current Release

The upgrade chapter in the HP XC System Software Installation Guide (Task 1: Prepare for the Upgrade) recommends that you install all relevant patch kits for the current release before upgrading to Version 3.1. This step is not required.

Save the LSF Configuration and Customizations Before Upgrading

Before upgrading the current system, save the LSF /hptc_cluster/lsf/conf/configuration directory. Also save any other known LSF customizations, such as elim scripts.

Compare the Final LSF configuration. After the cluster_config portion of the upgrade has completed, compare the final LSF configuration with the saved version to ensure that only the appropriate changes relevant to the upgrade have occurred. Also ensure (or restore, if required) the elim scripts. HP recommends that you use another terminal window to install the elim scripts at the point when the cluster_config utility displays the following prompt:

All user specified configuration is complete.
  The Golden Image will be created next.
  [P]roceed, [Q]uit: 

Thus, changes to the /opt/hptc/lsf/top/6.2/ directory will be included in the golden image. This is the directory where elim scripts are expected to reside.

Any changes to the LSF configuration files in the /hptc_cluster/lsf/conf/ directory can occur after cluster_config has finished because this directory is not part of the golden image.

If the LSF version has changed, binary paths (including the $LSF_SERVERDIR directory, where elim scripts are expected to reside) have also changed.

Possible Failed RPM Dependencies Errors Seen During the preupgradesys Utility

The preupgradesys utility might report failed dependencies errors when it is trying to remove Myrinet, InfiniBand, and QsNet^II interconnect RPMs. To work around this problem, you must manually remove the appropriate RPM.

Myrinet

Remove the gm RPM if you see a message similar to the following:

error: Failed dependencies:
       libgm.so.0()(64bit) is needed by (installed)
lustre-lite-1.4.2-2.6.9_22.11hp.3sp.XCsmp_3.1.0_SFS_2.1_1.2.x86_64 

Use the following command to manually remove the gm RPM before proceeding to the next step in the upgrade process.

# rpm -ev --nodeps gm

InfiniBand

An InfiniBand RPM dependency failure looks similar to the following:

Removing infiniband RPM and directories
error: error: Failed dependencies:
Failed dependencies:
        ibhost-biz is needed by (installed) paracomp-ib-1.1-beta2.x86_64
        ibhost-biz is needed by (installed) paracomp-ib-1.1-beta2.x86_64 

Use the following command to manually remove the ibhost-biz RPM before proceeding to the next step in the upgrade process.

# rpm -ev --nodeps ibhost-biz

QsNet^II

If you encounter a dependency failure with the QsNet^II RPM, use the following command to manually remove the qsnetdiags RPM before proceeding to the next step in the upgrade process.

# rpm -ev --nodeps qsnetdiags

The upgradesys Utility Might Fail While Backing Up the Database

The upgradesys utility invokes the managedb backup command to back up the current database. If a database table is corrupted, the mysqldump fails with the following error message:

Backing up database to
/opt/hptc/etc/sysconfig/upgrade/upgradesys.dbbackup-20061101164854.sql ...
mysqldump: Got error: 1016: Can't open file: 'CPUTotalsLog.MYI' (errno: 145)
when using LOCK TABLES 
Could not perform backup: 
Bad file descriptor at /opt/hptc/database/sbin/backup line 83, 
<CONF> line 12.
Can't dump databases: Bad file descriptor at /opt/hptc/sbin/upgradesys 
line 127, <STDIN> line 1. 

If this failure occurs, run the following command to correct the database tables:

# myisamchk -r /var/lig/mysql/*.MYI

After the database tables are corrected, invoke the upgradesys utility again.

The hptc-ire-serverlog Service Might Not Start

The hptc-ire-serverlog service is responsible for logging node configuration (nconfig) and imaging events to the /hptc_cluster/adm/logs/imaging.log file. Follow this procedure to verify that the service is running. If it is not running, start the service.
