Configuring Tru64 5.1B UNIX AdvFS parameters

You must change the Tru64 5.1B UNIX AdvfsIORetryControl parameter to prevent Tru64 UNIX advanced file system (AdvFS) from losing access to Lenovo Storage V series volumes.

As a result of temporary path loss, the AdvFS might lose access to the Lenovo Storage V series volumes. Therefore, the AdvfsIORetryControl parameter must be changed from its default value of 0, as shown in Figure 1.

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 Figure 2.

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
