IBM TOTAL STORAGE DS8000 - Manual (Page 115)

Action
Configure one or more additional extent pools, and then resubmit the task.
CMUG00123E The selected storage complexes do not exist in the
current configuration.
Explanation
You began to delete one or more storage complexes from an enterprise, but the
enterprise configuration changed or the enterprise was closed before you completed
the task for the following possible reasons:
v The storage complexes were deleted from another session.
v The enterprise was closed and you are now configuring another enterprise.
v The network connection to the storage complexes failed.
Action
Close the current panels and reopen the enterprise. If the problem persists, contact
IBM technical support for assistance.
CMUG00124E Invalid logical volume size. See the help text for
this message for valid sizes.
Explanation
The specified volume size is not supported on all platforms. Supported logical
volume sizes are microcode level dependent.
For DS microcode levels 5.0.3 and above:
v Supported Enterprise Storage System (ESS) logical volume sizes range from 0.1
to 982.2 decimal gigabytes (1GB = 10^9 bytes). You can calculate the exact
number of 512 byte blocks as INT((INT(GBx10^9/512)+63)/64)x64. The size of
the volume that is created on the ESS is identical to the size of the volume that
is created on the DS.
v Supported DS logical volume sizes range from 1 to 2048 binary gigabytes (1GB
= 2^30 bytes). This allocation uses the storage capacity of DS systems most
efficiently.
v Supported block logical volume sizes range from 1 to 4 binary gigablocks (1
gigablock = 2^30 512-byte blocks). If a specified size matches a supported DS or
ESS logical volume size, the volume is identified as a DS or ESS logical volume,
even though it is created by specifying the blocks volume type.
v Supported iSeries logical volume sizes are expressed in decimal gigabytes (1GB
= 10^9 bytes):
A0 (8.6 GB protected) A81 (8.6GB, unprotected)
A02 (17.5 GB protected) A82 (17.5 GB unprotected)
A04 (70.5 GB protected) A84 (70.5 GB unprotected)
A05 (35.1 GB protected) A85 (35.1 GB unprotected)
A06 (141.12 GB protected) A86 (141.12 GB unprotected)
A07 (282.25 GB protected) A87 (282.25 GB unprotected)
For DS microcode levels 5.0.1 and 5.0.2, block logical volume sizes must be a
multiple of 128, and ESS logical volume sizes must be in the following list:
