Sysback recreating logical volumes with 15 char names
Demetri has sysback version 126.96.36.199 and he has booted from his
full system backup and selected a non-root volume group. Then
he has selected numerous logical volumes from the logical volume
list and changed various information (indicating for some of
them not to create it). Then when he tried to select a logical
volume thats name was longer that the logical volume field (he
can tell this because the logical volume name was truncated),
he then got garbage on the rest of his screens. He got expr
syntax errors. Also, he tried to go back to the main menu and
then it only recognized the rootvg and not his non-rootvg. At
this point Demetri believes that there is some limit for logical
volume names that is not corresponding with aix's limit and that
this is causing his problem. Demetri is in the process of
rebooting from the sysback backup and will start customizing
the logical volumes thats names are not truncated.
He would like a call back from the sysback engineer to discuss the
possibility that sysback is broken.
LVM limits the filenames to 15 characters, so I'm not sure
how he got LV names that were so large. Maybe they were created
on a prior AIX level before the limit was enforced.
In any event, Sysback assumes a 14-character limit. I have applied
a fix to allow any length of names, and am in the process of
Have left message for customer to call back to find out how the
fix should be distributed. We can overnight mail or FTP if they
