Product Issues and Limitations
The following describes known problems with products included with HP Serviceguard Storage
Management Suite Version A.01.01 and workarounds for them. This is subject to change without
notice.
SCSI-3 Persistent Reservation Support
Veritas Cluster Server (VCS) relies on SCSI-3 Persistent Reservation being supported on the
storage. This is part of the Veritas split brain prevention. HP Serviceguard uses a different and
more robust method to prevent split brain, there is no need for SCSI-3 Persistent Reservation on
the storage.
The mknod Command Is Not Supported with CFS
You cannot use the mknod command to create devices on a cluster mounted file system - attempts
to use the mknod command will return Invalid argument.
Use of mount Commands for CFS Environments
Once the disk group and mount point multi-node packages are created in Serviceguard, it is
critical to use the cfs commands, including cfsdgadm, cfsmntadm, cfsmount, and
cfsumount. If the general commands such as mount and umount are used, it could cause serious
problems such as writing to the local file system instead of the cluster file system.
Any form of the mount command (for example, mount -o cluster, dbed_chkptmount,
orsfrac_chkptmount) other than cfsmount or cfsumountin a HP Serviceguard Storage
Management Suite bundle environment with CFS should be done with caution. These non-cfs
commands could cause conflicts with subsequent command operations on the file system or
Serviceguard packages. Use of these other forms of mount will not create an appropriate
multi-node package which means that the cluster packages are not aware of the file system
changes.
