HP XP7 RAID Manager Reference Guide (T1610-96064)

DescriptionOption
the specified raw_device is contained in two or more groups, the command is executed for the
first group.
Searches whether the specified LDEV is included in a group on the configuration definition file
(local instance). If it is in the group, the target volume is executed as the paired logical volume
-d[g] <seq#>
<LDEV#> [MU#]
(-d) or group (-dg). This option is effective without specification of '-g <group>' option. If the
specified LDEV is contained in two or more groups, the command is executed on the first group.
The <seq #> <LDEV #> values can be specified in hexadecimal (add the '0x' prefix) or decimal
notation. For XP7, specify the number of which 300,000 is added to the serial number for
<seq#>.
Displays the LDEV/STLBA/ENLBA number in hexadecimal.-fx
Displays the relation between the Device_File and the paired volumes, based on the group (as
defined in the local instance configuration definition file). If Device_File column shows 'Unknown'
-fd
to HOST (instance), then the volume is not recognized on own HOST, and raidvchkdsp command
is rejected in protection mode. Non-permitted volume is shown without LDEV# information (LDEV#
'-').
Displays the serial# and LDEV# of the external LUNs mapped to the LDEV for the target volume
by adding to last column (ignores the format of 80 column).

When RAID Manager starts, HORCM_DEV in horcm.conf is translated from Port/target/lun
numbers to the CU:Ldev information, on one hand HORCM_LDEV in horcm.conf is translated
-c
from the CU:Ldev information to Port/target/lun numbers, because RAID needs to specify 'Port#,
Targ#, Lun#' and 'LDEV' for specifying the target device, and then HORCM keeps this information
as internal database for the configuration.
If a storage administrator changes the LDEV to LUN/port mapping, such as
• a new/different LDEV is mapped to a previously used port/LUN, or
• an LDEV is mapped to a different/new port
then pair operations might be rejected because the new mapping is different from the mapping
information of the database in the running RAID Manager instance. A pairdisplay command
shows the real LDEV mapping at the time of the command execution and hence shows different
information than what is stored in the internal database of the RAID Manager instance.
The '-c' option for raidvchkdsp allows you to see if there is a difference between the current
running RAID Manager instance information and the real mapping. This indication should be
used to find such issues which indicate that:
• the RAID Manager instance should be restarted to discover and use the new mapping
information, or
• a configuration change occurred without changing the affected configuration files of the
RAID Manager instance.
Example change from LDEV#785 to LDEV#786:
# raidvchkdsp -g VG000 -c
Group PairVol Port# TID LU Seq# LDEV# LDEV#(conf) -change-> LDEV#
VG000 vg0001 CL4-E-0 0 17 63528 786 785(conf) -change-> 786
# raidvchkdsp -g VG000 -c -fx
Group PairVol Port# TID LU Seq# LDEV# LDEV#(conf) -change-> LDEV#
VG000 vg0001 CL4-E-0 0 17 63528 312 311(conf) -change-> 312
Example remove LDEV#785 from a port:
# raidvchkdsp -g VG000 -c
Group PairVol Port# TID LU Seq# LDEV# LDEV#(conf) -change-> LDEV#
VG000 vg0001 CL4-E-0 0 17 63528 - 785(conf) -change-> NO LDEV
# raidvchkdsp -g VG000 -c -fx
Group PairVol Port# TID LU Seq# LDEV# LDEV#(conf) -change-> LDEV#
VG000 vg0001 CL4-E-0 0 17 63528 - 311(conf) -change-> NO LDEV
