Toshiba POS SSD Life Monitor Drivers for Linux

Version 1.2

This package is the Toshiba POS SSD Life Monitor Drivers for Linux 1.2 instrumentation. This package monitors fixed Solid State Disks on an Toshiba POS system to determine when the number of writes to an SSD is reaching lifetime maximum.

Package Install

The toshiba-ssddrv-suse-1.2.0-1.0.i586.rpm contains the user mode libraries and support files that form the instrumentation. This rpm requires that the sblim-sfcb cimserver package is already installed.

% rpm -ivh toshiba-ssddrv-suse-1.2.0-1.0.i586.rpm

This will install the ssddrv libraries, update the SFCB repository with class definitions for RSS_SSDLifeMonitor and RSS_SSDLifeMonitorFailureImminent CIM classes.

Remote Management Agent Support - RMA 2.6

Most Toshiba customers will want to use RMA to allow interconnection of the instrumentation CIM classes to remote systems management software such as IBM Director. After install of the instrumentation the RMA General Agent daemon on the POS machine should be stopped and restarted in order to pick up cimserver repository and other system changes.

Configuration

The drivers have three configuration options available by editing the /etc/ssddrv/ssddrv.ini file.

• PercentUsedThreshold - Threshold for SSD %used over which an event is fired to registered client

  min=10% max=100% default 95%

• PollRate - Rate at which SSD %used value is polled to see if it is over threshold

  default is every 10 seconds

• SptLogAccess - Use SAT: 'SCSI Pass Thru' for ATA Log access. This works better than using 'ATA SMART Pass Thru' method for Linux. Set to '0' to switch to 'ATA SMART Pass Thru'.

  default is '1' On

Support Logging

The drivers log abnormal conditions to /var/log/ssddrv/ssddrv.log. For normal production usage there is no need to change this behaviour. In fact it is not recommended. If any problems surface however additional information may be logged for purposes of support.

To enable detailed logging edit the /etc/ssddrv/log.conf file. Change the Level property to 4 to enable very detailed trace logging. You may also wish to change the MaxLength property if you wish to log for any length of time as the logfile will fill quickly. Recycle the SFCB cimserver so that the instrumentation libraries pick up the logger configuration changes.

Log Levels:

• 0 - Off
• 1 - Error
• 2 - Information (default)
• 3 - Debug
• 4 - Trace

OS Support

• SLED 11 SP2/3
• SLES 11 SP2/3
• SLEPOS 11 SP2/3

Known Issues

• The drivers will not work for RAID arrays of SSDs at this time
• The drivers will not work if the ATA Controller setting in BIOS is set to "IDE" mode. Set to "AHCI" or "RAID"-capable depending on your Toshiba POS system
