配置 Tru64 5.1B UNIX AdvFS 参数

您必须更改 Tru64 5.1B UNIXAdvfsIORetryControl 参数，以防止 Tru64 UNIX 高级文件系统 (AdvFS) 失去对系统卷的访问权。

由于丢失临时路径，AdvFS 可能失去对系统卷的访问权。因此，必须更改 AdvfsIORetryControl 参数的缺省值 0，如Figure 1 所示。

Figure 1. 设置 AdvfsIORetryControl 参数

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

为防止重新引导后重置 AdvfsIORetryControl 参数，请在 Figure 2 中输入参数。

Figure 2. 维护 AdvfsIORetryControl 参数的示例输入

# 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
