Promise VTrak:RAID ヘッド:Xsan (メタデータ、ジャーナル、およびデータ)

この記事では、Promise VTrak RAID コントローラを Xsan 用 (メタデータ、ジャーナル、およびデータ) 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: Xsan (Metadata, Journal and Data)
#
# Script Details: builds 4 LUNs from 16 drives (head unit only)
# in the recommended configuration for use with Xsan 2
#
# 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]
