Limitations of the InForm OS CLI
stat/hist commands could exit SSH sessions on large configuration systems.
A new CLI environment variable <histanum> has been added for the stat/hist commands. The
value of <histanum> is used to determine how many records to show at a time for stat/hist
commands. If it is set to 0, then the stat/hist commands will show 5000 records at a time. The
sorting of the records is limited to the <histanum> records. For example, if <histanum> is set to
1000, then the sorting will be for every 1000 records of the output.
To set the value of <histanum>, use the showclienv and setclienv commands.
If the system configuration is large and <histanum> is set to be more than 5000, then it is possible
that a SSH session cannot run the command because of memory limit. In that case, the stat/hist
commands (statvv, histvv, statvlun, histvlun, statch, histch, statld, histld)
will exit with error message There is not enough memory to run this command on the system. Please
use the CLI remote client to run it. Exiting the command. In this case, run the command from a
remote CLI session.

If a system configuration is large, tunepd may not be able to run in the SSH session because of
the memory limit. It will exit with the error message There is not enough memory to run this command
on the system. Please use the CLI remote client to run it. Exiting the command. In this case, run the
command from a remote CLI session.
statvlun exits if there is insufficient memory to run an SSH session
If the storage system has too many VLUNs, statvlun could run out of memory in an SSH session.
In this case, it will return the following error message and exit: There is not enough memory to run
this command on the system. Please use the CLI remote client to run it. In this case, run the command
from the remote InForm OS CLI client.
