Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

The following are examples of using the command to enable I/O on an array port:
# vxdmpadm enable enclosure=HDS9500V0 portid=1A
# vxdmpadm enable pwwn=20:00:00:E0:8B:06:5F:19
Renaming an enclosure
The vxdmpadm setattr command can be used to assign a meaningful name to an
existing enclosure, for example:
# vxdmpadm setattr enclosure enc0 name=GRP1
This example changes the name of an enclosure from enc0 to GRP1.
Note: The maximum length of the enclosure name prefix is 23 characters.
The following command shows the changed name:
# vxdmpadm listenclosure all
ENCLR_NAME ENCLR_TYPE ENCLR_SNO STATUS

Configuring the response to I/O failures
You can configure how DMP responds to failed I/O requests on the paths to a
specified enclosure, disk array name, or type of array. By default, DMP is configured
to retry a failed I/O request up to five times for a single path.
To display the current settings for handling I/O request failures that are applied
to the paths to an enclosure, array name or array type, use the vxdmpadm getattr
command.
See “Displaying recovery option values” on page 192.
To set a limit for the number of times that DMP attempts to retry sending an I/O
request on a path, use the following command:
# vxdmpadm setattr \
{enclosure enc-name|arrayname name|arraytype type} \
recoveryoption=fixedretry retrycount=n
