Some of that is outside of my control
This is the method that was decided upon... we have become pretty endeared to using recovered Virtual Machines or volumes from our Production side; overall it has reduced our RTO significantly due to the ease of importing synchronized data.
Part of the long standing issue we have had with maintaining the OS portion at the DR site is changes made in production that don't get replicated to the DR environment. Those changes are supposed to be done, but often still get missed. While there is always the 'so and so forgot to...' and then management whines about it; doing a full replication of even the boot environments simply factors out those human problems. For instance - a new mount point is added or an old mount point is removed.. a ton of little annoying things. Then when we test out DR processes, sometimes these 'little things' that we are unaware were changed, can cost us large amounts of time. Lately, we have been consolidating ZPOOLS on Solaris and every time we test - we run into issues with them.
But overall this works very well. Everything is 100% except for this /boot MPATH issue; and honestly - the systems will run on a single path just fine. But you know.. that's not good enough for a geek such as myself! lol
Thanks for your input too

vfstab
vfstab(4) File Formats vfstab(4)
NAME
vfstab - table of file system defaults
DESCRIPTION
The file /etc/vfstab describes defaults for each file system. The information is stored in a table with the following column headings:
device device mount FS fsck mount mount
to mount to fsck point type pass at boot options
The fields in the table are space-separated and show the resource name (device to mount), the raw device to fsck (device to fsck), the
default mount directory (mount point), the name of the file system type (FS type), the number used by fsck to decide whether to check the
file system automatically (fsck pass), whether the file system should be mounted automatically by mountall (mount at boot), and the file
system mount options (mount options). (See respective mount file system man page below in SEE ALSO for mount options.) A '-' is used to
indicate no entry in a field. This may be used when a field does not apply to the resource being mounted.
The getvfsent(3C) family of routines is used to read and write to /etc/vfstab.
/etc/vfstab can be used to specify swap areas. An entry so specified, (which can be a file or a device), will automatically be added as a
swap area by the /sbin/swapadd script when the system boots. To specify a swap area, the device-to-mount field contains the name of the
swap file or device, the FS-type is "swap", mount-at-boot is "no" and all other fields have no entry.
EXAMPLES
The following are vfstab entries for various file system types supported in the Solaris operating environment.
Example 1 NFS and UFS Mounts
The following entry invokes NFS to automatically mount the directory /usr/local of the server example1 on the client's /usr/local directory
with read-only permission:
example1:/usr/local - /usr/local nfs - yes ro
The following example assumes a small departmental mail setup, in which clients mount /var/mail from a server mailsvr. The following entry
would be listed in each client's vfstab:
mailsvr:/var/mail - /var/mail nfs - yes intr,bg
The following is an example for a UFS file system in which logging is enabled:
/dev/dsk/c2t10d0s0 /dev/rdsk/c2t10d0s0 /export/local ufs 3 yes logging
See mount_nfs(1M) for a description of NFS mount options and mount_ufs(1M) for a description of UFS options.
Example 2 pcfs Mounts
The following example mounts a pcfs file system on a fixed hard disk on an x86 machine:
/dev/dsk/c1t2d0p0:c - /win98 pcfs - yes -
The example below mounts a Jaz drive on a SPARC machine. Normally, the volume management software handles mounting of removable media,
obviating a vfstab entry. Specifying a device that supports removable media in vfstab with set the mount-at-boot field to no (as shown
below) disables the automatic handling of that device. Such an entry presumes you are not running volume management software.
/dev/dsk/c1t2d0s2:c - /jaz pcfs - no -
For removable media on a SPARC machine, the convention for the slice portion of the disk identifier is to specify s2, which stands for the
entire medium.
For pcfs file systems on x86 machines, note that the disk identifier uses a p (p0) and a logical drive (c, in the /win98 example above) for
a pcfs logical drive. See mount_pcfs(1M) for syntax for pcfs logical drives and for pcfs-specific mount options.
Example 3 CacheFS Mount
Below is an example for a CacheFS file system. Because of the length of this entry and the fact that vfstab entries cannot be continued to
a second line, the vfstab fields are presented here in a vertical format. In re-creating such an entry in your own vfstab, you would enter
values as you would for any vfstab entry, on a single line.
device to mount: svr1:/export/abc
device to fsck: /usr/abc
mount point: /opt/cache
FS type: cachefs
fsck pass: 7
mount at boot: yes
mount options:
local-access,bg,nosuid,demandconst,backfstype=nfs,cachedir=/opt/cache
See mount_cachefs(1M) for CacheFS-specific mount options.
Example 4 Loopback File System Mount
The following is an example of mounting a loopback (lofs) file system:
/export/test - /opt/test lofs - yes -
See lofs(7FS) for an overview of the loopback file system.
