if this is still an issue ...

1) There are SCSI new disk array compatible with my servers HP-UX 10.20? most scsi disk arrays designed for enterprise environments should have compatibility lists that you can verify for compatibility with your OS as well as your hardware. you can also check with HP directly to see if they know which new 3rd party -- if that is your preference -- scsi disk arrays are backward-compatible with your servers.

2) Can I use a disk array that comunicate via network and mounted it as a shared disk? research SANs and NAS devices. verify with your dba and/or database application vendor documentation to see if database application is compatible with such setups.

3) Or what other solution can you recommen me? if an OS upgrade is not an option, i strongly suggest looking at SANs and NAS devices. if your database is that important, it is foolhardy to go about using it without an easily recoverable redundant setup.

4) In other topics, have you ever run HP-UX 10.20 in a virtual machine? Can you tell me wich one ? hp-ux 10.20 was optimized for PA-RISC servers and they came out back around 1999 when virtualization was not yet an enterprise class option (from what i remember anyways) so i do not think you will see it on VMware anytime soon.

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME

       mkqdisk - Cluster Quorum Disk Utility

WARNING

       Use of this command can cause the cluster to malfunction.

SYNOPSIS

       mkqdisk [-?|-h] | [-L] | [-f label] [-c device  -l label] [-d [-d ...]]

DESCRIPTION

       The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.

OPTIONS

       -c device -l label
	      Initialize  a new cluster quorum disk.  This will destroy all data on the given device.  If a cluster is currently using that device
	      as a quorum disk, the entire cluster will malfunction.  Do not run this on an active cluster  when  qdiskd  is  running.	 Only  one
	      device  on  the  SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
	      RAID array is used for quorum disk redundancy).  The label can be any textual string up to 127 characters - and is therefore  enough
	      space to hold a UUID created with uuidgen(1).

       -f label
	      Find the cluster quorum disk with the given label and display information about it.

       -L     Display information on all accessible cluster quorum disks.

       -d     Increase debugging level.  Specify multiple times for more information.  Currently, specifying more than twice has no effect.
