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:

vSupported 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.

vSupported 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.

vSupported 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.

vSupported iSeries logical volume sizes are expressed in decimal gigabytes (1GB

=10^9 bytes):

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:
