Solution 231801 : Persistent Reservation Commands Processed Slowly
on Sun StorageTek Arrays May Cause Loss of Access or Timeouts to
Filesystems
Bug ID: 6639618
Product
Sun StorageTek 6140
Sun StorageTek 6540
Sun StorageTek Flexline 380
Date of Preliminary Release: 15-Feb-2008
Date of Resolved Release: 10-Sep-2008
SA Document Body
Persistent Reservation Commands Processed Slowly on Sun StorageTek Arrays
May Cause Loss of Access or Timeouts to Filesystems
1. Impact
Sun StorageTek 6140, 6540 and Flexline 380 arrays attached to servers
running cluster software that employs the SCSI-3 reservation commands
of "PrIN" or "PrOUT" may see severe performance degradation, general
loss or application loss of filesystem access, and command timeouts to
devices serviced by the affected arrays.
2. Contributing Factors
This issue can occur on the following platforms:
* Sun StorageTek 6140 Array running firmware without 06.60.11.10
(maintenance update) or 07.10.25.10 (feature update) or later
firmware
* Sun StorageTek 6540 Array running firmware without 06.60.11.10
(maintenance update) or 07.10.25.10 (feature update) or later
firmware
* Sun StorageTek Flexline 380 Array without 06.60.11.20 or
07.10.25.10 or later firmware
connected to servers running:
* Sun Cluster 3.x (for Solaris 8, 9 or 10) with three(3) or more
nodes in the cluster
* Windows 2000/2003 using cluster software
Note: All versions of Sun Cluster 3.x and earlier that use SCSI-3
reservation commands may be affected by this issue.
3. Symptoms
Two basic symptoms can occur:
On the host:
1) The hosts show that filesystems experience hangs, performance loss,
or loss of access. Sun Clusters typically show a SCSI timeout on one
or more LUNs, or cause filesystems to unmount.
Solaris Example from /var/adm/messages:
Nov 15 16:53:06 myhost
/scsi_vhci/ssd@g600a0b8000325ad200004c07471f48c6 (ssd719):
Command Timeout on path /pci@11,700000/SUNW,emlxs@0/fp@0,0 (fp1)
Nov 15 16:53:11 myhost scsi: [ID 107833 kern.warning] WARNING:
/scsi_vhci/ssd@g600a0b8000325ad200004c07471f48c6 (ssd719):
Nov 15 16:53:11 myhost SCSI transport failed: reason 'timeout':giving
up
Nov 15 16:53:11 myhost Cluster.scdpmd: [ID 977412 daemon.notice] The
state of the path to device: /dev/did/rdsk/d62s0 has changed to FAILED
Windows Cluster Example:
17/12/2007 17:25:13 ClusSvc Error Resource Monitor
1145 N/A myhost Cluster resource Disk BD1 (L:)
timed out. If the pending timeout is too short for this resource,
consider increasing the pending timeout value.
17/12/2007 17:25:13 ClusSvc Error Resource Monitor
1145 N/A myhost Cluster resource Disk F: timed
out. If the pending timeout is too short for this resource, consider
increasing the pending timeout value.
2) The array shows NO ERRORS in the array Event Log during the period
of time that the host system(s) had their symptoms.
Notes:
1. Typically, SCSI-3 Persistent Reservations are performed during
volume/LUN management on the array, cluster failover, array path
failover. Any of these actions may be a catalyst for this issue.
2. Other standalone or clustered hosts using the same array can be
impacted by this issue, as all IO to the array from any host will
be affected.
4. Workaround
There is no workaround for this issue.
5. Resolution
For 6140, 6540, and Flexline 380 arrays staying with the 06.xx
firmware
6.60.11.10 is bundled with Sun StorageTek Common Array Manager(CAM)
6.1.0 or later:
CAM can be downloaded from
http://www.sun.com/downloads or
http://www.sun.com/download/index.jsp?tab=2#S
For 6140, 6540, and Flexline 380 arrays using Sun StorageTek
SANtricity, customers wishing to get firmware 06.60.11.10 or later
Please contact Sun Support for the firmware release bundle. You will
also need to get a new copy of SANtricity 10.10. Please order it
from: https://www2.sun.de/dct/forms/reg_us_1508_643_0.jsp
For 6140, 6540, and Flexline 380 arrays going to the 07.10 firmware
feature release
07.10.25.10 firmware is a feature release and requires a service call
for an upgrade. It is not bundled with CAM or SANtricity.
CAM 6.1.0 or later is required
SANtricity 10.10 or later is required
Please contact Sun Support if you require the 07.10 feature release
update.
