Issue Description:
Systems with large quantities of UDWIS/SBus Host Adapters installed (Sun part
number 370-2443-01) may not come up after reboot due to miscommunication
between
the SCSI host and the target. Large configurations with many UDWIS/SBus Host
Adapter cards are more vulnerable due to higher probability of encountering
the reboot problem.
If a system can be rebooted it may fail to communicate correctly with a storage
device connected via a UDWIS/SBus Host Adapter. This would have different
results depending on the system configuration.
StorEdge A3x00 units on either standalone systems or clusters are particularly
susceptible to this problem. Cluster or Non-cluster systems with StorEdge
A3x00s may see corrupted SCSI inquiry strings during boot up.
Example of corrupted SCSI inquiry strings;
Nov 1 13:55:49 test unix: sd2044 at QLGC,isp17: target 4 lun 0
Nov 1 13:55:49 test unix: sd2044 is /sbus@5d,0/QLGC,isp@1,10000/sd@4,0
Nov 1 13:55:49 test unix: Vendor 'SoEG', product '00****7*********',
(unknown capacity)
Moreover, if a node in a cluster system is running while the other booting
node is experiencing this problem, the running node will eventually be
affected with some StorEdge A3x00 controllers being failed over by the
booting node.
+ Determining System Affectivity.
To determine if a system is affected check the isp-fcode value as follows...
At the ok prompt;
dev
.properties
device-end
When .properties executes, examine the value of the property "isp-fcode".
It should be "1.28 99/11/08" for the 1.28 FCode image.
One can also get the version at the OS prompt via "prtconf -v", and looking
at the value for the same property.
EXAMPLE 1 (The command for an Ultra-2 with old UDWIS at Sbus slot 1 and
expected output from the ok prompt using (dev inquiry) would be);
ok> reset-all
ok> dev /sbus@1f,0/QLGC,isp@1,10000
ok> .properties
scsi-initiator-id 00000007
clock-frequency 03938700

EXAMPLE 2 (Same system running Solaris 8 using prtconf -pv commmand
produces the following output);

+ End of Determining System Affectivity.
Root cause analysis has determined that the problem is within the Fcode
level 1.25.
Corrective action was made available by the release of new Fcode level 1.28
via ECO# WO_16478 on November 24, 1999 by dash rolling the UDWIS/SBus Host
Adapter from 370-2443-01 to 370-2443-02. This new Fcode was made available
in Enterprise Services via LEAP 1071A.Implementation:
---
| | MANDATORY (Fully Pro-Active)
---
---
| X | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| | UPON FAILURE
---Replacement Time Estimate:
30 minutes
Special Considerations:
1. This problem is seen more often on systems with CPU module(s) of higher
clock speeds, and/or in systems with mutliple UDWIS/Sbus Host Adapters
installed. Reference FINI0547-1 for additional background information
on this issue.
2. Proactive implementation is authorized in mission-critical accounts
with E10000, E5x00, E6x00, and clusters. The probability of failure
is low in most configurations except for those with many UDWIS cards.
3. WARNING! Systems may experience "invalid command" during probe-scsi-all
and "invalid command" during "boot -hv" from the StorEdge D1000 with a
UDWIS card (with fcode 1.28) attached to StorEdge D1000 with the
following OBP variables set;
setenv diag-switch? true
setenv diag-level max
This is not a bug and the messages can be ignored. Reference FINI0569-1
for more information.Corrective Action:
For Cluster System configurations please follow the recommended procedure
in removing one node from the cluster for maintenance. Evaluate each
account to determine if this change applies. Problem can affect any E10000,
clustered HA, or multi-initiator configurations which can include D1000,
A1000, A3x00, or A7000 Sun Storage products, as well as SCSI attached
OEM storage products.
Review FINI0552-1 and, if appropriate, implement FIN's corrective action
prior to implementing this FCO.
Upon failure or request in mission-critical accounts with E10000, E5x00,
E6x00 and clusters, replace all 370-2443-01 (UDWIS SPORT-20D SBus card)
with 370-2443-02 (or above).
Upon failure, in all other configurations, replace all 370-2443-01 (UDWIS
SPORT-20D SBus card) with 370-2443-02 (or above).
Billing Type:
Warranty: Sun will provide parts at no charge under Warranty
Service. On-Site Labor Rates are based on how the
system was initially installed.
Contract: Sun will provide parts at no charge. On-Site Labor Rates
are based on the type of service contract.
Non Contract: Sun will provide parts at no charge. Installation by
Sun is available based on the On-Site Labor Rates
defined in the Price List.
--------------------------------------------------------------------------Implementation Footnote:
________________________
i) In case of Mandatory FCOs, Enterprise Services will attempt to contact
all known customers to recommend the part upgrade.
ii) For controlled proactive swap FCOs, Enterprise Services mission critical
support teams will initiate proactive swap efforts for their respective
accounts, as required.
iii) For Replace upon Failure FCOs, Enterprise Services partners will implement
the necessary corrective actions as and when they are required.
