Help page
showsys - Show system information.
SYNTAX
showsys [options]
DESCRIPTION
The showsys command displays the HP 3PAR Storage system properties such as
a system name, serial number, and system capacity information.
AUTHORITY
Any role in the system
OPTIONS
-d
Specifies that more detailed information about the system is displayed.
-param
Specifies that the system parameters are displayed.
-fan
Displays the system fan information.
-space
Displays the system capacity information in MB (1024^2 bytes).
-domainspace
Displays the system capacity information broken down by domain in MB
(1024^2 bytes).
-desc
Displays the system descriptor properties.
-devtype FC|NL|SSD
Displays the system capacity information where the disks must have a
device type string matching the specified device type; either Fast
Class (FC), Nearline (NL), Solid State Drive (SSD). This option can
only be issued with the -space option.
SPECIFIERS
None.
NOTES
See setsys command for information on setting the threshold parameters
indicated by the Value column in the output for showsys -param.
In the output for showsys -param, (from configured settings) indicates that
the system parameters displayed have been successfully read from the
Persistent Repository (PR). If the PR is not available (most likely because
of problems with the admin volume), the output reads (from default settings)
and the values displayed would indicate the system defaults. When (from
default settings) is displayed, system parameters cannot be updated.
If the VVRetentionTimeMax is 0, then the volume retention time in the system
is disabled.
For the system capacity information, there might be some overlaps among
Volumes, System, and Failed Capacities.

Tuning
Move VVs between CPGs
Move volume to another CPG using tunevv
Balance PDs
If allocation of physical diskspace is not in balance through disks available.
Dry-Run:
tunenodech -dr -debug -f -maxchunk 8 -chunkpct 5 -node 0 -devtype FC -fulldiskpct 1 -chonly
NO Dry-Run:
tunenodech -waittask -debug -f -maxchunk 8 -chunkpct 5 -node 0 -devtype FC -fulldiskpct 1 -chonly

Do this for all Nodes in your 3PAR environment after each other!! Just replace '-node 0' by '-node N' |

Move volume to another CPG using tunevv
Assuming I want to move a virtual volume (VV12_AO) to another new CPG (FC_r6):
tunevv usr_cpg FC_r6 VV12_AO
The logical disks used for user space are moved to CPG FC_r6 for virtual volume VV12_AO
Keep in mind that this will destroy your current AO. If the Volume has been moved to some Tier0 storage, let's say SSD disks,
the AO optimization for the volume gets lost and it will have to wait for the next AO runs.
If you want to move the VV regions that reside on Tier1 storage only, use:
tunevv usr_cpg FC_r6 -src_cpg FC_r5 VV12_AO
Assuming I want to move a volume (VV12_AO) to another new SnapCPG (FC_Snap):
tunevv snp_cpg FC_Snap VV12_AO
Unfortunatly you will have to run both commands seperatly. As of the documentation they can't be combined.
