3.3 CONFIGURING RAID 3.3.1 Quick Setup This is the easiest way to configure your SurfRAID LC16, but all parameters will be setup as defaults. If you want to change the default value, you have to go to customizing setup to change it. -
Page 23: Raid Params Menu
6 RAID Funcs 3.3.2.1 RAID Params MENU RAID Params menu configures the SurfRAID LC16 for the different supported RAID levels. To avoid accidentally erasing an existing configuration you must specify, using the “Re-Conf RAID” option, if you want to change the configuration. -
Page 24: Scsi/Fibre Params Menu
SCSI ID and the termination must be set to avoid causing a conflict with the SCSI adapter or other SCSI device daisy chained with the SurfRAID LC16. Command Tag Queuing is a function that allows a SCSI device to queue multiple requests without having to serialize the operations. This frees the control- ler to process requests in whatever order is convenient, instead of blindly processing and acknowledging each disk operation before starting the next. - Page 25 Use to setup each Slice to map a logical Lun Number. B. SurfRAID LC16.200F The “Fibre Params” consists of two categories. Each category is used to configure an independent FC-AL of the SurfRAID LC16 subsystem. The following shows the both categories. Each category has sub-menus and options. 3. Fibre Param...

Use to setup each Slice to map a logical Lun Number. 3.3.2.3 RS232 Params MENU The RS232 Params menu configures the external ports of the SurfRAID LC16. The SurfRAID LC16 can communicate with a remote terminal and modem. The SurfRAID LC16 and the remote terminal must be set to the same communication settings (baud rate, stop bit, data bit, and parity). -
Page 27: System Params Menu
3.3.2.4 SYSTEM Params MENU The System Params menu configures the internal operation of the SurfRAID LC16. To avoid having the configuration altered by unauthorized personnel, you can enable password protection to enter Configu- ration Mode. Also, to have the SurfRAID LC16 provide failure event notification use the Pager Info., FAX Info, and Company Info options. -
Page 28: Nvram
3.3.2.5 NVRAM The NVRAM menu options control the configuration information. When using this menu option, the SurfRAID LC16 should be off-line. NOTE: Any changes made in this group will cause data on the drives to be permanently erased. Once a configuration change has been made, the NVRAM (where the settings are stored) must be updated. - Page 29 Use this to view the current settings saved in NVRAM, get a statistical analysis of the read and write operations, plus the percentage of cache hits.
