|
||||
# Usage:
|
||||
#
|
||||
# This script is to discover disk devices.
|
||||
#
|
||||
# Input parameter : <PCI_ID> or nothing
|
||||
#
|
||||
# Output : disk and RAID arrys information
|
||||
#
|
||||
# Examples:
|
||||
# 1. When PCI_ID value is 1014:034a, execute "diskdiscover 1014:034a", the output format is as following:
|
||||
#
|
||||
# PCI_ID=1014:034a
|
||||
# ----------------------------------------------------------------------------
|
||||
# PCI_SLOT_NAME Resource_Path Device Description Status
|
||||
# ------------- ------------- ------ ----------- ---------------------------
|
||||
# 0001:08:00.0 0:0:0:0 sg0 0 Array Member Active
|
||||
# 0001:08:00.0 0:0:1:0 sg1 Function Disk Active
|
||||
# ---------------------------------------------------------------------------
|
||||
# Get ipr RAID arrays by PCI_SLOT_NAME: 0001:08:00.0
|
||||
# ---------------------------------------------------------------------------
|
||||
# Name PCI/SCSI Location Description Status
|
||||
# ------ ------------------------- ------------------------- -----------------
|
||||
# sda 0001:08:00.0/0:2:0:0 RAID 0 Disk Array Optimized
|
||||
#
|
||||
# 2. Execute "diskdiscover", the output format is as following:
|
||||
#
|
||||
# --------------------------------------------------------------------------
|
||||
# PCI_ID PCI_SLOT_NAME Resource_Path Device Description Status
|
||||
# ------ ------------- ------------- ------ ----------- ----------------
