Impact

On Sun StorEdge 3310, running Sun StorEdge Configuration Service (SSCS) in-band and sccli(1M) in-band at the same time may cause SCSI errors on servers. This can cause I/O issues and the server may require a reboot.

Note: SSCS is a graphical means of managing the SE3XXX family of products. sccli(1M) is the Command Line Interface (CLI) means of managing the same products.

Contributing Factors

This issue can occur on the following platform:

SPARC Platform

Sun StorEdge 3310 SCSI Array without firmware 4.13b (as delivered in patch 113722-11)

with the following:

Sun StorEdge Configuration Service (SSCS) and sccli(1M)

Note: SSCS, sccli(1M) and the glm(7D) driver are not Solaris version dependent.

This issue occurs when the following two conditions are met:

1. At least the following two daemons must be running on the monitoring server, verified by using the following command:

$ ps -ef | grep ss
root   370     1  0 08:08:21 ?        0:05 /usr/sbin/ssserver
root   374     1  0 08:08:21 ?        0:36 /usr/sbin/ssmon

2. In-band operation has to have been selected for the GUI which can be verified using the following command:

% grep "PRIAGENT_OVER_INBAND=" /var/opt/SUNWsscs/ssagent/ssagent.cfg
PRIAGENT_OVER_INBAND=0

Note: 0 = in-band selected (default); 1 = out-of-band selected

Symptoms

Should the described issue occur, messages similar to the following will be logged to the "var/adm/messages" file:

Workaround

To work around this issue, run either SCCS or sscli(1M) "out-of-band". The document "Sun StorEdge 3000 Family Configuration Service 1.5 User's Guide" part number 817-3337-12 page 103, chapter title: "To Use Out-of-Band Management," describes how to configure out-of-band management.

Resolution

This issue is addressed on the following platform:

SPARC Platform

Sun StorEdge 3310 SCSI Array with firmware 4.13b (as delivered in patch 113722-11 or later)
