ACSLS connection to LMU is unstable, and continually re-connects, and then resets. (Doc ID 2740365.1)

Last updated on JANUARY 04, 2021

Applies to:

Sun StorageTek Auto Cartridge Sys Lib SW (ACSLS) - Version 8.4 and later
Information in this document applies to any platform.
The ACSLS server would not start. All components started, except the acsls component, which would eventually timeout, causing the ACSLS startup to terminate.


The $ acsss enable command terminates when attempting to start the acsls component.

The ~acsss/log/acsss_event log showed the following errors:

2020-12-28 04:41:00 ACSLH[0]:

With the above 4 messages repeating every minute, until $ acsss enable timed out.

The ACSLS server was able to successfully ping and traceroute the <SL8500 IP address>.
Also, the command:
$ testlmutcp <SL8500 IP address>
correctly returned:
LMU Responded, compat level 23.


 There were no SL8500, ACSLS, or network changes.
