Can I safely ignore any mismatch_cnt errors on my Fusion-io array?

The root user of a system using Linux software RAID-1 or RAID-10 of Fusion-io ioDrives (aka IBM High IOPS SSD Adapters) may occasionally receive a message similar to the following:

/etc/cron.weekly/99-raid-check:

WARNING: mismatch_cnt is not 0 on /dev/md0

For RAID-1 and RAID-10 arrays using Linux software RAID, these messages are normal and considered a known bug in Red Hat Enterprise Linux 5. These messages will be removed in a future release of the operating system.

How do I increase the maximum email size in postfix?

The postfix MTA is configured by default with resource limits that safeguard the stability of the server. One such parameter is the maximum email size, which is configured to approximately 10 MB by default. If you need to send emails larger than 10 MB:

  • Backup the /etc/postfix/main.cf configuration file
  • Edit the /etc/postfix/main.cf configuration file
  • Add a line to the bottom of the file with the desired new size. For example, if you wish to increase the size to approximately 25 MB:
message_size_limit = 25000000
  • Save the file
  • Reload sendmail
service postfix reload

For more information, please refer to the postfix documentation.

How do I configure an IBM dumb terminal?

NOTE: The IBM 3151 or 3153 dumb terminals are end-of-life and therefore not supported by IBM or Eclipse. If you need a terminal for your server, please see Where can I buy an IBM dumb terminal for my IBM pSeries server?

How to configure an IBM 3151 or 3153 dumb terminal (aka console):

  • Press Control-“-“ (the minus key) to get to the setup screen
  • Verify the following settings:
  • Emulation = Wyse 50+
  • Enhanced = on
  • Comm Mode = Full duplex
  • Host/Printer = EIA/None
  • EIA Baud Rate = 19200 (9600 for older servers)
  • AUX Baud Rate = same as EIA
  • Language = US
  • EIA Data Format = 8/1/N
  • Aux Data Format = 8/1/N
  • Sessions = One
  • To save the settings and exit, press Control-“-“ (the minus key)

Note: the keys pressed must be the control in the lower-left part of the keyboard and the minus sign in the upper-right (numeric keypad).  If CONTROL-MINUS does not work, try CONTROL-SETUP or CONTROL-SCROLL-LOCK.  To navigate around, use the arrow key.  The space bar will present a list of options.

Can I adjust the number of no dial tone failures before VSI-FAX disables the modem?

Yes. You may adjust the number of nodials encountered before disabling the modems in the /u2/vsifax/lib/vsisrv.ini file, under the VFXSCHED section, by setting the max-no-dials value to something other than the default value of 3.
