vxdisk export operation fails if length of hostprefix and device name exceeds 30 characters (3543668)
If the combined length of the hostprefix and the device name exceeds 30 characters, the vxdisk export operation fails with the following error message:
VxVM vxdisk ERROR V-5-1-18318 Device c6t50060E8005655501d86s2: Name too
long for export. Length of Hostprefix + Disk accessname should not exceed
30 characters. Please see vxdctl(1M) man page for information on setting
user-specifed hostprefix.

Workaround:
Use the enclosure-based naming (EBN) scheme instead of the operating system naming (OSN) scheme. OSN naming typically contains more characters and is not as intuitive. If the EBN name combined with the hostprefix exceeds 30 characters, you can manually set the hostprefix to a smaller size using the
vxdctl set hostprefix=value command, where value is the new hostprefix.
