3. 2004 ADIC 11 Upgrade Guidelines When upgrading to AMASS 5 4 please make note of the following upgrade guidelines Operating a System Upgrade Guidelines HP Tru64 To successfully install AMASS while using only part of a disk as the AMASS cache you must first verify that the c partition of the disk has a file system type fstype of unused Second you must verify that the user amass has read write permission to the raw c partition for example dev rdisk dsk2c You can get this permission by owning the file belonging to a group that owns the file or allowing access to all users of the file NOTE If you do not perform these two verifications when attempting to start AMASS you may get a message in the tac log that says the cache is invalid Upgrade Instructions X Note Before upgrading your software and or firmware ADIC recommends that the AMASS database be backed up prior to performing the upgrade X Note The following tasks are presented as guidelines only because the actual steps 12 are site specific For pre installation instructions for a specific storage device refer to the Accessing Storage Devices book Make sure the UNIX server has the required operating system patch levels Read the hard disk partitioning space requirements and guidelines on partitioning the cache in the Getting Started chapter in Installing AMASS Make sure the cache is empty by running the sysperf command and veri
