Upon completion of this module, you should be able to:
Describe the Sun StorEdge T3 Array boot process
List the plug-in Silicon Operating System(pSOS) commands
Configure environmental parameters
Upgrade the Sun StorEdge T3 Array firmware
Create redundant array of independent disks(RAID) volumes on the Sun StorEdge T3 Array
Configure global system parameters
Enable array fault monitoring
The Boot Process
EPROM flash-memory device(FMD) contains code that functions as the system boot loader
FMD supports three boot modes:
none-Boots the EPROM firmware; does not load the controller software
tftp-Loads the controller software from a tftp boot server
auto-Loads the RAID software from the master control system area on the default boot disk(uldl)
The default bootmode parameter is set to auto
The FMD is responsible for booting the RAID software, which is normally stored in a reserved partition on the master controller's drives. The FMD can also load the RAID software from any server on the network using the tftp protocl.
In the event the Sun StorEdge T3 Array fail to boot from its local disks due to corrupted or inaccessible RAID firmware, you can use the procedure in configuring a tftp boot server as a method of recovery
Updating the Master Control System Area
To place a copy of the RAID controller firmware in the system area reserved on all disks in the master controller unit, enter:
T3:/:<1>boot -i nb101.bin
Verifying Firmware Levels
The four different types of firmware are:
RAID controller
EPROM
Disk drive
UIC
Connect to Sun StorEdge T3 Array using a telnet session
Type ver to identify controller firmware level
Type fru list to identify disk drive, UIC, and EPROM firmware levels
Upgrading the Array's Firmware
Retrieve the firmware files from
web site
File names at the time of this writing are:
nb101.bin-RAID controller firmware
ep2_10.bin-EPROM firmware
lpc_04.11-UIC firmware
ST118202F.d33a.fw-FC-AL drive firmware
Use these commands to upgrade the firmware:
boot-Upgrades the RAID controller firmware
ep-Upgrades the EEPROM firmware
lpc-Upgrades the UIC firmware
disk-Upgrades the disk module firmware
To upgrade the RAID controller firmware, enter:
T3:/:<1>boot -i nb101.bin
To upgrade the EEPROM, enter:
T3:/:<2>ep download ep2_10.bin
To upgrade the UIC, enter:
T3:/:<3>lpc download u111 lpc_04.11
T3:/:<4>lpc download u112 lpc_04.11
To upgrade the disk modules, enter:
T3:/:<5>disk download uldl-9 ST118202F_d44a.fw
Modifying Global System Parameters
Global system parameters include the following:
Cache block size
Partner group multipathing
Cache mode
Mirrored cache
LUN reconstruction rate
Volume verification
Cache read-ahead threshold
The cache buffers are allocated on a least-recently-used(LRU) basis. The state of any cache buffer can be:
Empty-The cache buffer has not been allocated and has no previous data in it
Clean-The cache buffer has been allocated and filled with data that has been written to disk
Dirty-The cache buffer has been allocated and filled with data; however, it has not been written to disk
Creating RAID Volumes
Volume configuration parameters include:
Volume name
Volume size-Range of drives(und1-d9)
RAID level-RAID 0,1,or 5
Hot-spare availability-Can only use Disk Drive 9(und9)
Volumes cannot be reconfigured, only created or deleted
Use the vol add command to create the volume
t3:/:<1>vol add volume-name data undn-n raid n standby und9
The pSOS environment provides a suite of basic UNIX commands for file manipulation and directory navigation. The pSOS environment does not provide a file editor. You must edit all files on an administration host, and then use ftp to copy them to the Sun StorEdge T3 Array
Three set commands direct syslog system messages:
set logto-Configures the destination
set loglevel-Filters the generated messages
set logmask-Not for general use
