• On S2A6620s the Li-Ion battery bounced between state before it worked properly.
DE5129
• The Li-Ion firmware upgrade on an S2A6620 would not attempt to upgrade the
battery’s firmware if the battery pack is failed even if a firmware upgrade is
required to return it to service. DE5205
• When the Li Ion battery on the S2A6620 was in ROM mode due to a failed
firmware upgrade, the battery would be reported missing. DE5207
• When logging into the controller via the CLI, an error message indicating that the
CLI was unable to create shared memory would result in the login being refused.
DE5224
• There was an issue that caused intermittent controller reboots on the SFA12K-
20E. DE5420
• On the SFA 12000, infrequent false power supply errors would cause the
controller to switch from write-back caching mode to write-thru mode. 4583
5.0 Known Issues
5.1 Common
• The drive serial number reported in SHOW PD output may contain additional
characters that are not on the disk label. The serial number on the disk label will
always be contained within the potentially more verbose string reported by SFA
OS.
• The GUI management agent included in the SFA OS supports Microsoft’s Internet
Explorer v9.0 in compatibility mode only. See the Compatibility Guide for the
supported browsers.
• 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.
To find the offline device, issue the command:
lsscsi | awk -F/ '{print $NF}' | while read a; do printf "%s " $a; cat
,/sys/block/$a/device/state; done
To bring the device back online, issue the command:
#echo running > /sys/block/<sd??>/device/state and #multipath -r
where you replace <sd??> with the appropriate sd, for example sdaf, found from
the previous command.
A workaround for this issue is to update these packages:
o device-mapper:1.02.74-10.e16
o device-mapper-multipath: 0.4.9-56.el6_3.1.x86_64
DDN recommends that you install these as soon as possible.
