Updating sd.conf configuration file (Solaris 11.x x86 and 11.4 SPARC)
About this task
The sd.conf host file is used to control options for SCSI disk storage device.
Steps
1.
Run the following command to verify the sd.conf file location:
#ls /etc/driver/drv/
2.
If the file is not in the expected location, run the following command to copy it from
/kernel/drv
:
# cp /kernel/drv/sd.conf /etc/driver/drv
3.
Run the following commands to create a backup copy and modify the file:
# cp -p /etc/driver/drv/sd.conf /etc/driver/drv/sd.conf_ORIG
# vi /etc/driver/drv/sd.conf
Example
Below are the entries that are recommended for PowerStore storage.
sd_max_xfer_size=0x100000;
sd-config-list = "DellEMC PowerStore", "throttle-max:64, physical-block-size:4096,
disksort:false, cache-nonvolatile:true";
Parameter
Description
Value
sd_max_xfer_size
Restrict SCSI disk driver maximum I/O
size to 1 MB
0x100000
sd-config-list
SCSI inquiry storage response, the VPD
for PowerStore LUNs
DellEMC PowerStore
throttle-max
Maximum SCSI queue depth setting
64
physical-block-size
Optimal LUN block size in bytes
4096
disksort
SCSI device command optimization
false
cache-nonvolatile
Indicate whether the storage has a
nonvolatile cache
true
Post configuration steps - using the PowerStore
system
When host configuration is complete, you can access the PowerStore system from the host.
You can create, present, and manage volumes accessed from the host via PowerStore Manager, CLI, or REST API. Refer to the
PowerStore Manager Online Help
,
CLI Reference Guide
, or
REST API Reference Guide
for additional information.
