What are the Solaris Host recommendations for Supporting HUK 6.2
Applies to
Fresh installation of Solaris 11.4
Answer
- Solaris 11.4, the FC driver binding is changed from ssd to sd. Additionally, the configuration files reside in
/etc/driver/drv
and not in/kernel/drv
. - Associated with the driver binding change, the node name in the private /devices path is changed from
ssd@
to thegeneric disk@.
- By default, the host_config utility that comes with the NetApp Host utilities, modifies the
/etc/driver/drv/ssd.conf
file. However, the configuration changes needs to be made to/etc/driver/drv/sd.conf
file. - Configuration present in
ssd.conf
has to be moved tosd.conf
as detailed in Oracle (Doc ID 2595926.1). Additionally, modify thessd stanza
tosd
in the file.
System configuration with and without HUK configured
OS settings before installation of HUK
root@Solaris_server:~# prtconf -v |grep NETAPP
value='scsiclass,00.vNETAPP.pLUN_C-Mode.r9121' + 'scsiclass,00.vNETAPP.pLUN_C-Mode' + 'scsiclass,00' + 'scsiclass' value='NETAPP'
root@Solaris_server# devprop -n /dev/rdsk/c0t600A098038314A714D2B555455313355d0s2 device-blksize device-pblksize

Procedure to be followed after installing HUK
- Post installation of HUK, run
host_config
command with appropriate arguments.
Example: For using Solaris Native multipathing (MPxIO), run
root@Solaris_server#/opt/NTAP/SANToolkit/bin/host_config -setup -protocol fcp -multipath mpxio
- The following lines will be added to the
/etc/driver/drv/ssd.conf
. We need to copy these to the/etc/driver/drv/sd.conf
. Additionally, we need to replacessd
stanza withsd
.
root@Solaris_server:/etc/driver/drv/# cp /etc/driver/drv/ssd.conf /etc/driver/drv/sd.conf
root@Solaris_server:/etc/driver/drv/# vi /etc/driver/drv/sd.conf
:%s/ssd/sd/g
- Validate the contents of
sd.conf
Example: Below is the output for multipath as MPxIO and DMP:
- For MPxIO
root@Solaris_server# cat /etc/driver/drv/sd.conf |grep NETAPP
sd-config-list="NETAPP LUN", "physical-block-size:4096, retries-busy:30, retries-reset:30, retries-notready:300, retries-timeout:10, throttle-max:64, throttle-min:8";
- For DMP:
root@Solaris_server# cat /etc/driver/drv/sd.conf |grep NETAPP
sd-config-list="NETAPP LUN", "physical-block-size:4096, retries-busy:30, retries-reset:30, retries-notready:300, retries-timeout:10, throttle-max:8, throttle-min:2";
- Reboot the server to take effect of all changes.
Status after host_config and changes with sd.conf file
root@sparc-s7-54-90:/etc/driver/drv# prtconf -v |grep NETAPP
value='NETAPP LUN' + 'physical-block-size:4096, retries-busy:30, retries-reset:30, retries-notready:300, retries-timeout:10, throttle-max:64, throttle-min:8'
root@sparc-s7-54-90:/etc/driver/drv# devprop -n /dev/rdsk/c0t600A098038314A714D2B555455313355d0s2 device-blksize device-pblksize

Note:
- If the system is upgraded from an earlier version of Solaris 11.3 or lower versions to Solaris 11.4, these changes are not required.
- For a fresh install of 11.4 and to modify the behavior to force Fibre Channel devices to bind to the SSD driver, add the following lines to the file(/etc/devices/inception_points) and reboot with the reconfiguration:
# scsa-no-binding-set-fcp
# scsa-no-binding-set-vhci
# swapgeneric-ssd-loads-sd
