M (megabytes)•
• G (gigabytes)
If the letter is omitted, the default unit is megabytes.
-s
Indicates that the migration should not occur, but the
hpvmmigrate command should check whether or not the
migration is possible. Because guests and their VM Hosts
are dynamic, a successful -s trial does not always
guarantee a subsequent successful migration. The
hpvmmigrate command with the -o, -s, and -h options
(but without a -p or -P option) checks host connectivity
and CPU compatibility for online migration.
-t
For offline migration, translates the storage device names
specified with the -m option by comparing WWIDs. To
compare WWIDs, the storage resources must be present
and available on both the source and the target VM Hosts.
If you specify the -t option before the first -m option, the
-t option applies to all -m options. The -t option
overrides the -T option for storage resources specified
with the -m option. Device translation is automatic for
online migration.
-T
For offline migration, specifies not to translate devices.
-v Displays the version number of the hpvmmigrate
command.
-w
For online migrations, bypasses all vswitch connectivity
checks. Use the -w option only of you are certain that the
source and target vswitches are connected to the same
subnet; otherwise, your active guest will lose network
connectivity after migrating.
-Y
Suppresses encryption negotiation and sends guest
memory data in the clear.
You can modify the default behavior by setting variables
in the /etc/rc.config.d/hpvmconf file using the
ch_rc command. The variable
HPVM_OVMM_ENCRYPT_BY_DEFAULT controls whether
any attempt at encryption negotiation is done. The default
setting of 1 attempts an encryption negotiation. The
variable HPVM_OVMM_ENCRYPT_ALGORITHM can be
changed from its default value of aes-128–cbc to aes-256–cbc
for sites with stronger security concerns.
If you do not specify either the -Y or the -y option, and
you set the HPVM_OVMM_ENCRYPT_BY DEFAULT variable
to its default setting of 1, the target-host-alisas-or-IP-addr
name given to the -h option for an online migration is
examined to see whether it matches the private network
convention for guest migration. If the name given ends in
—hpvm-migr, or if such a name was chosen because of
finding a match in the /etc/hosts file, encryption is
suppressed for the private network. The default is to
encrypt guest data for all other connections. Explicit use
of the -Y or -y option, as well as changing the
