Hi bjjdad73, I've also studied RCADM a bit in the hope of getting notifications via eMail about some newly created RAID Arrays.
rcadm --follow --help says:
rcadm -F
FOLLOW
------
Long form:
rcadm --follow [--test-mail --mail-address <to_email_address>
--mail-server <email_server>
--from-user <from_email_address>] [--syslog]
Short form:
rcadm -F [-tm -ma <to_email_address> -ms <email_server>
-fu <from_email_address>] [-sl]
Long form:
rcadm --follow --delay <seconds>
[--mail-address <to_mail_address> --mail-server <email_server>
--from-user <from_email_address>]
[--program <program>]
[--scan] [--syslog]
Short form:
rcadm -F -d <seconds>
[-ma <email_address> -ms <email_server> -fu <from_email-address>]
[-p <program>] [-s] [-sl]
OPTIONS
-------
-tm, --test-mail
Sends a test email message. Used with the --mail-address, --mail-server, and
--from-user flags.
-ma, --mail-address
Specifies the email address to notify when an event occurs, such
as a disk failure or an array going offline. Also specifies an
email address to which to send an email test message.
-ms, --mail-server
Specifies the email server to send mail through.
-fu, --from-user
Specifies the sender's email address for email notifica-
tion. Used with the --mail-address option when sending email
alerts.
-p, --program
Specifies the program to execute when an event occurs.
-sl, --syslog
Logs events with critical and error serverity levels.
-d, --delay
Specifies the number of seconds to wait between polling the
disks and arrays.
-s, --scan
Uses variables found in rcadm.cfg instead of command line arguments.
If the file exists, the values specified in the file are used unless
explicitly set otherwise on the command line. The file rcadm.cfg must
be in the same directory as rcadm.exe.
Example: MAILADDR <user@system.com>
MAILSERVER <email_server.com or IP address>
FROMUSER <user@system.com>
PROGRAM <program to run>
-l, --language
Specifies the language locale digit to print the messages.
Example: -l 0 /* English */
EXAMPLES
--------
Example: Poll for status every 30 seconds and logs event to system log
and send email when an event occurs.
rcadm -F --delay 30 --mail-address me@somesys.com
--from-user someone@somesys.com
--mail-server my-mail-server.com --syslog
Example: Poll for status every 60 seconds and run a program when an
event occurs.
rcadm -F --delay 60 --program myprog.exe
Example: Send a test message.
rcadm -F --test-mail --mail-address me@somesys.com
--from-user someone@somesys.com
--mail-server 192.168.0.1
So, how to add username and password for the mailserver? And what's about SSL/TLS?
Funny thing beside, in Raidexpert2 Ver. 6.1.5-00025 you have the Option to set eMail-notifications via "Options > Notification" (which by the way doesn't work for me as I always get the Error "Mail Server Connection Issue"):
All Data filled there will be saved as plain text (incl. Password!) in rc_cgi_config.txt...
