certain types of SCSI Target requests, but not enough memory is available to
allocate the resources.
SCOS-61444 User Interface During a controller failover, the option to rebalance ports might be displayed in
the Storage Manager Client before the Storage Center is ready to perform a port
rebalance.
SCOS-60535 User Interface A controller might reset because of the format and length of the Uniform
Resource Identifier (URI) string that is used when configuring Directory Services.
SCOS-62474 User Interface When the Summary tab for a Storage Type is selected in Storage Manager Client

Size is not a correct format might be displayed if the lowest index
disk in the Storage Type has more free space than other disks.
