Installation Issues
If you encounter any issues installing CFS, refer to the following paragraphs for typical
problems and their solutions. You can also refer to the HP Serviceguard Storage
Management Suite Release Notes and the HP Serviceguard Storage Management Suite
Read Before Installing document, if you encounter an issue that is not included here.
Incorrect Permissions for Root on Remote System
The permissions are inappropriate. Make sure you have remote root access permission
on each system to which you are installing.
Checking communication with system01............... FAILED
Remote reams/rcp permissions not available on: system01
Correct permissions and continue
Continue? [Y/N]:
Suggested solution: You need to set up the systems to allow remote access using ssh or
rsh.
NOTE Remove remote shell permissions after completing the CFS installation and
configuration.
Resource Temporarily Unavailable
If the installation fails with the following error message on the console:
fork() failed: Resource temporarily unavailable
The value of the nkthread tunable parameter may not be large enough. The nkthread
tunable requires a minimum value of 600 on all systems in the cluster. To determine the
current value of nkthread, enter:
# kctune –q nkthread
If necessary, you can change the value of nkthread using the System Management
Homepage (SMH) tool, or by running the kctune command. If you change the value of
nkthread, the kernel must be rebuilt for the new value to take effect. It is easier to
change the value using SAM because there is an option to process the new kernel
immediately. See the kctune(1M) manual pages for more information on tuning kernel
parameters.
Inaccessible System
The system you specified is not accessible. This could be for a variety of reasons such as,
the system name was entered incorrectly, or the system is not available over the
network.
Checking communication with system01................ FAILED
System not accessible : system01
Suggested solution: Verify that you entered the system name correctly; use the ping(1M)
command to verify accessibility of the host.
