InfoScale log file permissions

The following table lists the parameter values and the corresponding log file permissions that are applicable when those values are set. These values are applicable to all the InfoScale components.

Table: Tunable parameter values, file permissions, and behavior

Tunable parameter value

Log file permissions

Behavior

0 (default)

600

Update existing file permissions on upgrade.

1

640

Update existing file permissions on upgrade.

2

644

Update existing file permissions on upgrade.

3

Inherit umask

Update existing file permissions on upgrade.

10

600

Do not change existing file permissions on upgrade.

11

640

Do not change existing file permissions on upgrade.

12

644

Do not change existing file permissions on upgrade.

13

Inherit umask

See Setting log file permissions.

VxFS logging tunable configuration

Table: VxFS tunable parameter

InfoScale component

Tunable parameter

Located in file

VxFS

eo_perm

/etc/vx/vxfssystem

Use the following command to set this tunable parameter:

# /opt/VRTS/bin/vxtunefs -D eo_perm=<parameter_value>

You can also manually set the parameter value using the following command:

# cat /etc/vx/vxfssystem eo_perm <parameter_value>

After changing the permissions, restart the VxFS services, or reboot the system, for the changes to take effect.

VxVM logging tunable configuration

Table: VxVM tunable parameter

InfoScale component

Tunable parameter

Located in file

VxVM

log_file_permissions

/etc/default/vxsf

Use the following command to set this tunable parameter:

# vxtune log_file_permissions <parameter_value>

After changing the permissions, restart the VxVM services, or reboot the system, for the changes to take effect.

VCS logging tunable configuration

Table: VCS tunable parameter

InfoScale component

Tunable parameter

Located in file

VCS

VCS_ENABLE_PUBSEC_LOG_PERM

/opt/VRTSvcs/bin/vcsenv

For VCS, you can add the tunable with an appropriate value in the following file:

For example, # export VCS_ENABLE_PUBSEC_LOG_PERM=1.

After changing the permissions, restart the VCS service for the changes to take effect.

Run the following commands sequentially:

# hastop -local

# hastart

Note:

If there are other components under VCS control, for example, VxCPServ and VxFEN, then a VCS restart is required for the log file permissions changes of those components to take effect.

Alternatively, reboot the system for the changes to take effect.

VxCPServ logging tunable configuration

Table: VxCPServ tunable parameter

InfoScale component

Tunable parameter

Located in file

VxCPServ

VCS_ENABLE_PUBSEC_LOG_PERM

/etc/vxcps.conf

After changing the permissions, stop and restart the vxcpserv process for the changes to take effect.

If VxCPServ is configured under VCS control (if there is a VCS service group for VxCPServ), then restart VCS using the following commands sequentially:

# hastop -local

# hastart

Or, use # hastart -onenode, if the CP Server is configured in a single-node VCS cluster.

Alternatively, reboot the system for the changes to take effect.

DBED logging tunable configuration

Table: DBED tunable parameter

InfoScale component

Tunable parameter

Located in file

DBED

VCS_ENABLE_PUBSEC_LOG_PERM

/etc/vx/vxdbed/dbedenv

For example, # export VCS_ENABLE_PUBSEC_LOG_PERM=1.

After changing the permissions, restart the vxdbd daemon for the changes to take effect.

To enable the vxdbd daemon, run the following command:

# /opt/VRTS/bin/sfae_config enable

To disable the vxdbd daemon, run the following command:

# /opt/VRTS/bin/sfae_config disable

Alternatively, reboot the system for the changes to take effect.

InfoScale Operations Manager (IOM) logging tunable configuration

Table: IOM tunable parameter

Component

Tunable parameter

Located in file

IOM

log_file_permissions

/etc/opt/VRTSsfmh/log_file_permissions.conf

Use the following CPI command to set this tunable parameter:

# /opt/VRTSsfmh/bin/perl /opt/VRTSsfmh/bin/set_logfiles_permissions.pl --logfile_permission=<parameter_value>

Note:

The Inherit umask tunable value (13) is supported only on Linux.

After changing the permissions, restart the IOM services, or reboot the system, for the changes to take effect.
