Managing Serviceguard Sixteenth Edition, March 2009

This information is used in creating the mirrored disk configuration using Logical
Volume Manager. In addition, it is useful to gather as much information as possible
about your disk configuration. You can obtain information about available disks by
using the following commands:
• diskinfo
• ioscan -fnC disk or ioscan -fnNC disk
• lssf /dev/*dsk/*
• bdf
• mount
• swapinfo
• vgdisplay -v
• lvdisplay -v
• lvlnboot -v
• vxdg list (VxVM and CVM)
• vxprint (VxVM and CVM)
These are standard HP-UX commands. See their man pages for complete information
about usage. The commands should be issued from all nodes after installing the hardware
and rebooting the system. The information will be useful when doing storage group
and cluster configuration. You can mark up a printed listing of the output from the
lssf command to indicate which physical volume group a disk should be assigned
to.
Hardware Configuration Worksheet
You may find a worksheet such as the following useful for organizing and recording
your cluster hardware configuration. This worksheet is an example; blank worksheets
