CMUN02388E 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:
