symcfg show -sid $SID -pool $i -detail -thin -gb |grep "Max. Subscription Percent"
will return some line which include string Max. Subscription Percent and also Enable in same line ?
Have you tested the command and what is the output in this lines where is Max. Subscription Percent ?

If syntax is
Code:
if commandline
then
       # commandline exit code is 0 = ok
       echo ok
else # commandline exit code <> 0
       echo not ok
fi

[ is one of the commands. So it's also [[.
But also symcfg, cp, grep, awk, .. are commands.

Ex. testing how cp works
Code:
if cp file file2  >/dev/null 2>&1
then
      echo "cp done"
else
      echo "cp not so ok"
fi

So something: grep output to the /dev/null - not so interesting to see.
Code:
if symcfg show ... | grep  ...  >/dev/null 2>&1
then
    ...
fi

But you can also test output of grep.
Code:
data=$(symcfg show -sid $SID -pool $i -detail -thin -gb | grep "Max. Subscription Percent" )

# grep some value and if some line include also Enable then okay.
case "$data" in
        *Enable* ) echo "ok" ;;
        *) echo "not ok" ;;
esac

But if line include "Max. Subscription Percent" and "Enable" in this order, then why not using grep something like
Code:
grep "Max. Subscription Percent.*Enable"
# 
data=$(symcfg show -sid $SID -pool $i -detail -thin -gb | grep "Max. Subscription Percent.*Enable" 2>/dev/null)
[ "$data" = "" ] && echo "not ok"
[ "$data" != "" ] && 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.
