    echo "ok"
  else
    echo "not ok"
  fi
done < list_vmax_xx_pools

cat list_vmax_xx_pools

pool_1
pool_2
pool_3

You of course can, there's no syntax error, but the way you present it won't yield a reasonable result. symcfg may output whatever it wants, if you grep for "Max Subscription Percent" the output will never be an "Enable" alone.
Why don't you grep for "pool.*Max Subscription Percent" or even "pool.*Max Subscription Percent.*Enable" (as proposed by kshji) in the first place and then work on the results file? Or, maybe, that's already what you desired?
BTW, kshji's last data evaluation could be condensed to

Code:

[ -z "$data" ] && echo "not ok" || echo "OK"

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
