5 Known problems and limitations
This section provides a list of known problems and limitations as known to HP at the time of
publication. If workarounds are available, they are included.
5.1 Known problems and limitations in Serviceguard
• Persistent Reservation (PR) module pr_cntl internally uses the dmsetup info command to
probe /dev/dm-n devices. In SUSE Linux Enterprise Server 11 SP1, the dmsetup info
command does not support probing /dev/dm-n devices. Therefore, the features that use
/dev/dm-n, such as udev alias cannot be supported with PR. If you are using udev aliases
in serviceguard-xdc environment, then PR module cannot be supported with that configuration.
NOTE: This restriction is applicable only on SUSE Linux Enterprise Server 11 SP1.
• To use multipath devices you can configure the Serviceguard packages as follows:
In the case of Serviceguard A.11.20.00, if you are using multipath devices, HP
recommends you to exclude the PR module from the package configuration file. After
◦
Serviceguard is upgraded to A.11.20.20, you must generate the package configuration
file to include in the PR module. To enable PR protection, you must restart the package
with the new configuration file.
◦ In the case of Serviceguard A.11.20.10, PR module is included in the package
configuration file, but is ignored for multipath devices. After Serviceguard is upgraded
to A.11.20.20, you must re-apply and restart the package configuration to enable PR
protection.
IMPORTANT: Ensure that all the nodes are upgraded to Serviceguard A.11.20.20 before
reapplying the package configuration
