Working with HDS Command Utilities (cont)

• Bare metal installations and maintenance booting will require knowledge of location codes.

• Volume group management will require knowledge of PVID's, Hdisk names, and DLM names.

• The standard AIX utilities "lspv", "lsdev", "lsattr", and "lscfg" provide some of this information

• The Hitachi HDLM utilities exist in the directory "/usr/DynamicLinkManager/bin" on each SAN attached system.

• The primary HDLM tool for obtaining disk information is "dlnkmgr".

• Hitachi DLM utilities is an older HDS Command utility that still exists within the Mt Xia environment and has a separate set of command utilities

• Example scripts to generate this disk identification information exist at the following URL:

• /css/GlobalSysAdmin/AIX/dlmfdrvmap.shtml
