HP StorageWorks Storage Mirroring DNS Failover Utility (DFO) release notes (T2558-96089, February 2008)

username:
The user account’s domain name (optional; account running
program is used if missing)
password:
The user account’s password (optional)
machine: The machine that the DFO utility will run on when it runs with
/getpassword. In effect, this parameter locks the credentials
for use by a particular machine.
file: New location for the credentials file. By default, the
credentials file is stored as dfo_credentials.dat in the
current working directory
dnszonename:
The name of the
DNS zone or DNS container, used to refine
queries (opti
onal)
dnsdomain-
name:
The name of the DNS domain, used to refine queries (optional)
logfilename: The name of the log file (optional)
fbswitch: (optional)
fbswitch =
The DFO will only failback records in the dfo_failback_config.dat file.
fbswitch = forcemodify. The DFO will failback all records that match
the search criteria, even if they are not in the config file.
Also used if dfo_failback_config.dat file is missing
trusteename:
The domain account for the source server
machine (domain\machine$). DFO attempts to deny write
permissions to the DNS A record on failover for the
account identified as the trustee. “Deny write
permissions” is then removed from the DNS A record
on failback. This keeps the source server from
reclaiming its DNS A record if it comes back online
prior to failback. You can enter multiple
/trustee switches
(for example, /trustee administrator /trustee user)
(optional)
Seconds:
The number update interval for the TTL (in seconds)
Options
/failback
Denotes a failback procedure, performed after a
failed source is recovered or restored
(required for modify on failback)
/lock
Allows Active Directory locking for the A type record of the
source specified without modifying the record
/unlock
Allows Active Directory unlocking for the A type record of the
source specified without modifying the record
/verbose
Logging and display level set to maximum detail (optional)
/FLUSHDNS /machine [machine_FQDN]) Run the ipconfig /flushdns command to flush the DNS
cache on the specified machine (remote or local (.))
/addomain
<ADFQDN> (opt
ional) The name of the Active Directory domain where the
source A type r
ecord’s object is stored. This is used if the
Active Direct
ory Domain location of the DNS record object is different
than the DNS do
main name location for that object. The DFO utility will
attempt to loc
ate the Active Directory record object for
locking (see t
he “trusteename” for more information),
but if the DFO u
tility is unable to determine the location of the
Active Direct
ory object, it will use the
ADFQDN locati
on if specified.
/TTL
Update the TTL value of all modified records.
/test
Test mode. Modifications are NOT actually made, just listed
(optional)
