Installation issues • Linux install issue on RHEL 5: Under specific distributions, such as Red Hat Enterprise Linux 5, the installation CD is auto-mounted using the following CD Label: # /media/HpInstallx.x/ If this occurs, the CD may get mounted with the no execution flag, causing the installation script to fail. Installation failure may be indicated by the error message: # ./install_smb.sh bash: ./install_smb.sh: /bin/sh: bad interpreter: Permission denied Workaround: Manually unmount the installation CD. For example, if the CD was auto-mounted in /media/HpInstallx.x, issue the following commands to remount the CD: nl # unmount /media/HpInstallx.x # mkdir -p /mnt/cdrom # mount /dev/cdrom /mnt/cdrom If the unmount command fails with a busy warning, make sure you have closed all applications and consoles that could be using the CD media. • On Microsoft Windows Server 2008 the MSA2000 uses the native Microsoft MPIO.

EVA-specific issues • EVA configuration: The SSCM has the following restrictions when managing an EVA array: • Host definitions cannot be removed from the EVA by the SSCM. • Once a port (HBA) has been added to a host definition, the port cannot be removed by the SSCM. • HP Command View EVA offers great flexibility in how a user can configure an EVA. However, the SSCM may not operate as expected if an array was configured using HP Command View EVA. A user should use SSCM or HP Command View EVA to configure an array, but not both. NOTE: Using HP Command View EVA to delete unwanted entries in an array's configuration (such as a host or port that has been physically removed) is supported. 4
