Stripe Size Fault Tolerance
Fault-Tolerance Level Default (KB) Valid Stripe Sizes (KB)
Raid 0 128 8, 16, 32, 64, 128, 256
RAID 1/RAID 0+1 128 8, 16, 32, 64, 128, 256
RAID 5 16 8, 16, 32, 64*
* RAID 5 does not support stripe sizes larger than 64KB per drive.
Online RAID Level and Stripe Size Migration
To change the RAID level and stripe size without loss of data or system
disruption, use the Online RAID Level and Stripe Size Migration screen. From
this screen you can reconfigure a currently configured logical drive to a new
fault-tolerance (RAID) level or a new stripe size.
Novell NetWare Online Array Configuration Utility
The Novell NetWare Online Array Configuration Utility, also called
CPQONLIN, is an NLM for configuring your drive arrays without shutting
down your server. CPQONLIN also provides information about the status of
drives attached to the Integrated Smart Array Controller. This utility indicates
drive failure, expansion, or waiting for expansion or rebuild (queued). Before
loading CPQONLIN.NLM, you must load the appropriate device
driver
CPQARRAY.HAM. CPQONLIN.NLM is located in the ONLINE
directory of Novell SSD Disk 4. See driver installation information in the
NetWare section of Chapter 5.
Autoconfiguration
If no logical drives are configured, a CPQONLIN autoconfiguration wizard,
shown in the following figure, appears and prompts you to select fault-
tolerance information. CPQONLIN then configures arrays optimally for the
selected fault tolerance.
