1.0 Overview This document applies to the SFA OS version 2.1.1.2-18319 release for DataDirect Networks’ SFA12K-40, SFA12K-20, SFA12K-20E, SFA10K-X, SFA10K-E, and SFA7700 storage systems. It details upgrade procedures, enhancements, resolved issues, known issues with workarounds, and recommended practices associated with SFA OS 2.1.1.2. 2.0 Installation 2.1 Overview SFA OS version 2.1.1.2 is a new feature release for all supported systems. 2.
Prior to upgrading to 2.1.1.2, please identify your current BMC version and then check these notes: 1. If you have BMC version 21.54 or older, you must perform a manual BMC firmware update before you load the SFA OS 2.1.1.2 firmware. Refer to the SFA12K BIOS and BMC Firmware Update Field Bulletin, 96-00344-001. 2. The automatic update will take as long as 10 minutes. During that time, the SFA12K controller will be unresponsive and will not show progress.
Issue 'SHOW ENCLOSURE ALL' to identify your current BMC version. For example, see Figure 2.
4. Issue the command, SHOW UPS * ALL_ATTRIBUTES. You should see the message shown in Figure 4. Battery Mfg. Date: Thu Sep 8 4:10:30 2011 Battery Life Remaining: 730 days Figure 4 3.0 4.0 4.1 Enhancements • SFA7700: Added licensed feature, SFX Read. SFX Read support makes use of SSDs to to assist with servicing host I/O for re-reads residing in cache, and prefetch based on I/O patterns. • SFA12K-40 now supports up to 20 SS8460 enclosures. Resolved Issues Common These issues have been resolved. 4.
• The SS7000 enclosure does not support the SET SLOT xx POWER OFF command with enclosure firmware versions prior to 05.02.01. • In the SS7000, when removing an I/O module or cable under load, it is possible that one or more disks could be marked failed which would change the redundancy of the storage pools. This is due to in-flight I/O being timed out and retried before the IOC reports the drive as missing.
o If the ULA field has the value "0000000000000000", continue to wait and not issue any CLI commands besides "show controller".
• On SFA10K-E and SFA12K-20E, the CD-DVD_DEVICE attribute must be cleared after completing an installation and before restarting the stack. (DE7427) • On SFA12K-20E and SFA10K-E, VMs can be shown as running when a controller hosting those VMs goes down. (DE4409) In certain situations, if one controller in a couplet goes down, the remaining controller may show the VMs on the offline controller as running. This problem has been fixed. 5.4 SFA12K and SFA10K • When an SFA is upgraded from SFA OS v1.5.
• With RHEL6.2 and OFED 1.5.4.0 in an IB switch attached environment, it is possible that a virtual disk on a controller may not be added back to the multipath device map after a failover.
5.6 5.7 SFA10K • The SS2460 does not support SLOT POWER OFF feature and so the SET SLOT POWER command has no effect on drives in the SS2460. • The Management Ethernet port (LAN4) may boot running at 10 Mb/sec half-duplex, instead of 100 Mb/sec or 1000 Mb/sec full-duplex. Typically, full Ethernet port speeds can be restored by unplugging and replugging the Ethernet cable to the controller port experiencing the slow speed. If the issue persists, please contact support@ddn.com.
• Restarting a controller with an IPMI Power On command leaves CPU0_Temp as Not Available It is possible to remotely start the controller after a SHUTDOWN CONTROLLER or SHUTDOWN SUBSYSTEM, but doing so leaves the controller's CPU0_Temp as Not Available. Resolution: Manually restart the controller with the power button or by reseating the canister instead of using IPMI Power On command.
6.0 Recommended Practices The recommended best practices for SFA OS version 2.1.1.2 include: • SS6000 DEM and I/O module replacement. For SS6000 DEM and I/O module replacement, see the SFA OS User Guide for the procedures. • Reduce host I/O load during background initializations. When a storage pool is in the process of being initialized, a significant internal I/O load is generated. To avoid poor performance, DDN recommends that heavy host I/O loads be avoided until pool initialization has completed.
8.0 Support To submit debug information to DDN, use the diag tgz command. Diag is a captive account on SFA OS systems that is used for performing operations on a controller when there’s no CLI access or the CLI isn’t appropriate. Perform diag operations by using ssh to login to the diag account. The command syntax is: ssh diag@xxx.xxx.xxx.xxx diag-command (where xxx.xxx.xxx.xxx is the controller’s IP address and diag-commands are listed in Table 1.
