Promise VTrak:RAID コントローラおよび SAS 接続の拡張シャーシ - スペアのある直接接続の構成スクリプト

この記事では、Promise RAID コントローラおよび SAS で接続された拡張シャーシを、直接接続のストレージに構成するスクリプトを紹介します。

構成スクリプトを作成するには、以下のテキストにある「#Begin Copy」から「#End Copy」の間の行をコピーし、こちらのガイドライン にそって「テキストエディット」にそのテキストをペーストします。スクリプトを作成した後、こちらの記事 のガイドラインにそって、構成スクリプトを読み込みます。

# Promise VTrak E-Class configuration script
#
# Script Name: RAID Controllers and SAS-connected Expansion Chassis: Direct Attached
#
#
# Script Details: builds 4 RAID 5 LUNs from 32 drives (head unit only)
# for direct attached usage
# Script Assumptions: no arrays or logical drives created
# (uncomment out array deletion if needed)
# script works with either SATA or SAS configurations
#
#
# Global controller settings
# LUN Affinity: enabled [required]
# Adaptive Writeback Cache: enabled [optional]
# Host Cache Flushing: disabled [optional]
# Forced Read Ahead: enabled [optional]

# Delete any existing arrays
# Delete array 0 thru 3
# Note: uncomment out delete array commands to delete any existing LUNs;
# all physical drives must be available for script to run
