HP StorageWorks 2/140 - Director Switch Release Note page 13

Workaround
On a stable system after the diald software has run for a few cycles the discovery
information will remain unchanged. In order to minimize the opportunity for this
conflict to occur with any programs using ioscan, you can modify the polling
period to a larger value. To do this, the entry
"DIAL_DISCOVERY_DELAY"
in the file
/opt/sanmgr/hostagent/config/dial.cfg
should be changed. The polling period value should be specified in minutes, e.g. a
value of 60 would result in a 1 hour discovery poll cycle. The polling period value
should be modified considering the time and frequency that ioscans are being run,
in order to avoid diald and ioscan being executed simultaneously.
This issue will be corrected in the next release of director and edge switch
firmware.
