Adaptec SCSI RAID Software Reference Guide {scsi_device},{free_space}... Specifies any additional SCSI devices and associated freespaces used to create the volume set. A volume set can have a maximum of 16 partitions (or freespaces, since each freespace becomes a partition). Note that you must explicitly specify the entire ID for any additional SCSI devices (the SCSI channel number, device ID, and device logical unit number). Switches /cache{=boolean} Specifies whether to enable the array's raw array cache. You can use this switch only if a native operating system's file system (for Windows NT/Windows 2000 (basic disk only)/ Windows XP (basic disk only), the NTFS or FAT file system) resides on the array. If you do not want to enable the volume set's raw array cache when you create it, you can do so later by using the container set cache command. In fact, the container set cache command gives you more control in setting the NVRAM write-back cache. If you set this switch to TRUE, the command causes the controller to ■ Enable the read-ahead cache setting for the specified array. You should always enable the read-ahead cache to optimize performance, unless your application-which is unlikely-is doing completely random reads. ■ Enable when protected the NVRAM write-back cache setting for the specified array. This means the controller enables the array's NVRAM write-back cache only if a battery is present and its status is OK. This switch defaults to FALSE, which means the command causes the controller to disable the array's raw array cache. If you accept the default, the command ■ Disables the read-ahead cache ■ Disables the NVRAM write-back cache 5-36
