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"

vxmemstat

vxmemstat(1M)															     vxmemstat(1M)

NAME

       vxmemstat - display memory statistics for Veritas Volume Manager

SYNOPSIS

       vxmemstat [-e] [-i interval [-t count]]

DESCRIPTION

       The vxmemstat utility prints memory statistics information.  This information can be system-wide, or it can be specific to a Veritas Volume
       Replicator object.

OPTIONS

       -e	 Prints extended memory statistics.

       -i interval
		 Prints memory statistics every interval seconds.

       -t count  Prints the local system time every count intervals.  The time interval is specified using the -i interval option.

OUTPUT FORMAT

       The statistics are prefaced by a timestamp showing the current local time on the system. Statistics are printed as a one-line output record
       for each memory pool. The records are preceded by two header lines.  The output line consists of blank-separated fields. All numeric fields
       are in units of kilobytes.

       The following fields are displayed on each line:

       Pool	 Name of the memory pool. Memory consumers allocate memory from different pools for different purposes.

       DG	 Name of the disk group in which the RVG is present.

       Min Size  Minimum amount of memory always reserved for use by consumers of the pool. As consumers require more memory, additional memory is
		 allocated to the pool for distribution to them.

       Max Size  Maximum  amount  of memory that can be allocated to the pool. This is equal to the value assigned to the maximum pool size system
		 tunable that corresponds to the pool.

       In Use	 Amount of memory (out of that allocated) currently being used by consumers of the memory pool.

       Allocated Amount of memory currently allocated to the memory pool. The amount of memory allocated to a pool ranges between the minimum  and
		 the maximum pool size. The amount of allocated memory increases as more memory is needed and decreases as it is relinquished.

       Max Used  Maximum amount of memory used by consumers from this pool since system startup.

		 This field is not shown if the -e option is specified.

       Max Pool Used
		 Maximum  amount  of  memory used by consumers from this pool at any time since the last reboot. The value shows the maximum usage
		 even if usage by the pool has varied over this time period.

		 This field is shown if the -e option is specified.

       Waiting	 Indicates if any I/O is waiting to allocate memory from this pool.  This usually indicates that the corresponding tunable for the
		 maximum size of this pool needs to be increased.

		 This field is not shown if the -e option is specified.

       Waiters	 The number of requests that are waiting to allocate memory from this pool.

		 This field is shown if the -e option is specified.

EXIT CODES

       The  vxmemstat  utility exits with a non-zero status if the attempted operation fails.  A non-zero exit code is not a complete indicator of
       the problems encountered, but rather denotes the first condition that prevented further execution of the utility.

       See vxintro(1M) for a list of standard exit codes.

EXAMPLES

       To display statistics every 5 seconds and time stamp the output every alternate interval, use the command:

	      vxmemstat -i 5 -t 2
