Configuring Tru64 5.1B UNIX AdvFS parameters

You must change the Tru64 5.1B UNIXAdvfsIORetryControl parameter to prevent Tru64 UNIX advanced file system (AdvFS) from losing access to the system volumes.

As a result of temporary path loss, the AdvFS might lose access to the the system volumes. Therefore, the AdvfsIORetryControl parameter must be changed from its default value of 0, as shown in Setting the AdvfsIORetryControl parameter.

Figure 1. Setting the AdvfsIORetryControl parameter

# sysconfig -q advfs AdvfsIORetryControl
advfs:
AdvfsIORetryControl = 0
# sysconfig -r advfs AdvfsIORetryControl=2
# sysconfig -q advfs AdvfsIORetryControl
advfs:
AdvfsIORetryControl = 2

To prevent the AdvfsIORetryControl parameter from resetting after a reboot, enter the parameters in Example entries to maintain the AdvfsIORetryControl parameter.

Figure 2. Example entries to maintain the AdvfsIORetryControl parameter

# sysconfig -q advfs AdvfsIORetryControl > /tmp/advfs.out
# vi /tmp/advfs.out
advfs:
AdvfsIORetryControl=2

# sysconfigdb -af /tmp/advfs.out advfs

-> New entry in the /etc/sysconfigtab


# sysconfig -d advfs
advfs:
AdvfsIORetryControl = 2
