Working with HDS Command Utilities

• Each disk in the AIX environment has a variety of identities. These identities are used for different purposes. The identities include:

• Location Code
• PVID
• Hdisk Name
• DLM Name
• World Wide Name (WWN)
• LDEV

• To determine each of the disk identities requires knowledge of multiple tools, both AIX and Hitachi utilities.

• Communication with the Storage Management team will require WWN's and LDEV information for each disk.

For assistance with designing, implementing, and supporting your storage systems in a business continuity design structure, please contact Mt Xia.
