System Administrator’s Guide to Installing DataMgr

Requirements Make sure you read the DataMgr “Release Notes” to obtain the following information:

•A list of current patches and packages required by your servers.

•GUI requirements.

•Known problems.

•The latest AMASS compatibility matrix. Install a compatible version of AMASS on a server on your network to provide storage server resources.

Note

Install and start AMASS before installing DataMgr.

Prerequisites

File Pathname Limit

File System Size & Name

DataMgr supports a ﬁle pathname limit of 1023 characters for the DataMgr root directory in AMASS. For example, if client ﬁles are going under /archive/FMSclients/eureka on AMASS, then the length of this string (26 characters) must be subtracted from 1023 (1023-26=997). Consequently, succeeding ﬁle pathnames can be a total of 997 characters in length.

File system size is important. ADIC recommends that your ﬁle system not exceed 1 million ﬁles. As the number of ﬁles approaches 1 million, the system slows considerably. The smaller the ﬁle system, the faster most utilities and commands will complete.

The size of a ﬁle system name can be a maximum of 24 characters in length.
