Configuring AdvFS parameters on an HP AlphaServer Tru64 UNIX host system

This section describes how to modify and configure the Advance File System (AdvFS) parameters on a Tru64 UNIX host system.

Perform the following steps to prevent Tru64 AdvFS from losing access to DS6000™ disk drive modules, as a result of temporary path loss. For HP AlphaServer Tru64 5.1B, UNIX, you must change the AdvfsIORetryControl parameter. The default value is 0, and the range could be from 0 to 9.

Edit the sysconfig file and increase the number of AdvFS I/O retries, for example from 0 to 2.
```
# /sbin/sysconfig -r advfs AdvfsIORetryControl=2
AdvfsIORetryControl: reconfigured
```

Perform the following to prevent the parameter value from reverting to the default value of 0 after a system restart:

# 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
