Users and Roles
The traditional root account has been changed to a ’root’ role on all Oracle Solaris 11
installations as part of the Role Based Access Control (RBAC) feature set. This change gives
improved auditability across the operating system, and the ability for administrators to delegate
various system tasks to others in a safe way.
Revert root to a normal user account
# rolemod -K type=normal root
Configure root as a role (default)
# usermod -K type=role root
Configure root role to use the user password instead of root password
# rolemod -K roleauth=user root
Add a new user and delegate the System Adminstrator profile to the user
# useradd -m -P "System Administrator" joerg
Add a new user with a ZFS file system as the user’s home directory and add an entry in
auto_home
# useradd -m -d localhost:/export/home/joerg2 joerg2
# grep "joerg2" /etc/passwd
joerg2:x:101:10::/home/joerg2:/usr/bin/bash
# cat /etc/auto_home

File Systems - Basic ZFS Administration
Create a ZFS pool with a single disk
# zpool create testpool c3t2d0
Create a ZFS pool with 3 disks in RAID0 configuration
# zpool create testpool c3t2d0 c3t3d0 c3t4d0
Create a ZFS pool with 3 disks in RAID1 configuration
# zpool create testpool mirror c3t2d0 c3t3d0 c3t4d0
Create a ZFS pool with 3 disks in a RAIDZ configuration (single parity)
# zpool create testpool raidz c2t2d0 c3t3d0 c3t4d0
Create a ZFS pool with 1 disk and 1 disk as seperate ZIL (ZFS Intent Log)
# zpool create testpool c3t2d0 log c3t3d0
Create a ZFS pool with 1 disk and 1 disk as L2ARC (Level 2 Storage Cache)
# zpool create testpool c3t2d0 cache c3t3d0
Create a ZFS file system and share it via NFS:
# zfs create rpool/export/nfstest
# zfs set share.nfs=on rpool/export/nfstest
Share a files system via CIFS
# svcadm enable -r smb/server
# echo "other password required pam_smb_passwd.so.1 nowarn" \
>> /etc/pam.d/other
# passwd <username>
# zfs create -o nbmand=on rpool/export/smbservertest
# zfs share -o share.smb=on rpool/export/smbservertest%smb_st
# mkdir /export/smbservertest/archiv
# chown junior2 /export/smbservertest/archiv
Now you can access the share via smb://junior2:password@192.168.1.200/smb_st . You
have to set a new password for each user that wants to access a SMB share after adding the PAM
module
Use shadow migration
# pkg install shadow-migration
# svcadm enable shadowd
# zfs set readonly=on rpool/export/shadowmigtest
# zfs create \
-o shadow=file:///export/shadowmigtest rpool/export/shadowmigtestnew
Create an encrypted zfs dataset
# zfs create -o encryption=on rpool/export/secretproject
Change the wrapping key
# zfs key -c rpool/export/secretproject
Change the encryption key of a dataset
Please keep in mind that you can't set the encryption key to a user-defined value, you just can
initiate the generation of a new encryption key. The wrapping key encrypting the encrytion key can
be set to a user definable value.
# zfs key -K rpool/export/secretproject
How to limit the ZFS ARC cache (up to Oracle Solaris 11.1)
# echo "set zfs:zfs_arc_max=0x40000000" >> /etc/system
# reboot
How to limit the ZFS ARC cache (since Oracle Solaris 11.2)
# echo "set user_reserve_hint_pct=80" > /etc/system.d/arclimit
# reboot
The user_reserve_hint_pct parameter works differently than the old zfs_arc_max
parameter. This parameter doesn’t set a hard limit for the arc cache.This parameter defines
how much memory is reserved for application use. It therefore limits how much memory can
be used by the ZFS ARC cache.
This value is dynamic. So you can change this parameter while the system is running.
However it’s a best practice to change it to it in small steps to it’s intended final value. There is
a script doing it this way available with the MOS note 1663862.1.
You can get the current value of the parameter by using:

Change the wrapping key
# zfs key -c rpool/export/secretproject
Change the encryption key of a dataset
Please keep in mind that you can't set the encryption key to a user-defined value, you just can
initiate the generation of a new encryption key. The wrapping key encrypting the encrytion key can
be set to a user definable value.
# zfs key -K rpool/export/secretproject
How to limit the ZFS ARC cache (up to Oracle Solaris 11.1)
# echo "set zfs:zfs_arc_max=0x40000000" >> /etc/system
# reboot
How to limit the ZFS ARC cache (since Oracle Solaris 11.2)
# echo "set user_reserve_hint_pct=80" > /etc/system.d/arclimit
# reboot
The user_reserve_hint_pct parameter works differently than the old zfs_arc_max
parameter. This parameter doesn’t set a hard limit for the arc cache.This parameter defines
how much memory is reserved for application use. It therefore limits how much memory can
be used by the ZFS ARC cache.
This value is dynamic. So you can change this parameter while the system is running.
However it’s a best practice to change it to it in small steps to it’s intended final value. There is
a script doing it this way available with the MOS note 1663862.1.
You can get the current value of the parameter by using:

Clear Cache Memory in Linux
How to Clear Cache Memory in Linux
Find Memory Status
[root@localhost Desktop]# free -m
total used free shared buffers cached
Mem: 987 915 71 7 0 395
-/+ buffers/cache: 519 467
Swap: 1023 0 1023
In this example the total amount of available memory is 987 M. 519 M are used by processes and 467 M are free for other applications. Do not get confused by the first line which shows that 71 M are free! If you look at the usage figures you can see that most of the memory use is for buffers and cache. Linux always tries to use RAM to speed up disk operations by using available memory for buffers (file system metadata) and cache (pages with actual contents of files or block devices). This helps the system to run faster because disk information is already in memory which saves I/O operations. If space is needed by programs or applications like Oracle, then Linux will free up the buffers and cache to yield memory for the applications. If your system runs for a while you will usually see a small number under the field "free" on the first line.
Find Cache Memory uses in Linux
Use free command to find out cache memory uses by Linux system. Output of free command is like below
Last column is showing cached memory ( 395 MB) by system. -m option is used for showing memory details in MB’s.
[root@localhost Desktop]# free -m

3. Copy the /kernel/drv/fp.conf file to the /etc/driver/drv/fp.conf file.
Select one of the following to enable or disable specific FC HBA ports:
4. Add the following line for each FC HBA port that is to be enabled in the
/etc/driver/drv/fp.conf:
name="fp" parent="parent name" port=port-number mpxio-disable="no";
5. Copy the /kernel/drv/scsi_vhci.conf file to the /etc/driver/drv/scsi_vhci.conf file.
Edit the /etc/driver/drv/scsi_vhci.conf file to add the vendor ID and product IDentries.
The vendor ID and product ID are the vendor and product identification strings that the device
returns in SCSI INQUIRY data. The vendor ID must be eight characters long. You must specify
all eight characters even if the trailing characters are spaces.
The product ID can be up to 16 characters long.
scsi-vhci-failover-override =
"VendorID1ProductID1", "f_sym",
"VendorID2ProductID2", "f_sym",
...
"VendorIDnProductIDn", "f_sym";
Note that the entries are separated by the ’,’ character and the last vendor/product entry is
terminated by the ’;’ character.
For example, to add a device from a “ACME” vendor with a product ID of “MSU”, and to add a
device from vendor “XYZ” vendor with a product ID of “ABC”, you would add the following
lines to the /etc/driver/drv/scsi_vhci.conf file:
To add a device from a “XYZ” vendor with a product ID of “ABC”, you would add:
scsi-vhci-failover-override =
"ACME MSU", "f_sym",
"XYZ ABC", "f_sym";
Save and exit the /etc/driver/drv/scsi_vhci.conf file
For example,
scsi-vhci-failover-override =
"COMPELNTCompellent Vol", "f_sym";

3. Copy the /kernel/drv/fp.conf file to the /etc/driver/drv/fp.conf file.
Select one of the following to enable or disable specific FC HBA ports:
4. Add the following line for each FC HBA port that is to be enabled in the
/etc/driver/drv/fp.conf:
name="fp" parent="parent name" port=port-number mpxio-disable="no";
5. Copy the /kernel/drv/scsi_vhci.conf file to the /etc/driver/drv/scsi_vhci.conf file.
Edit the /etc/driver/drv/scsi_vhci.conf file to add the vendor ID and product IDentries.
The vendor ID and product ID are the vendor and product identification strings that the device
returns in SCSI INQUIRY data. The vendor ID must be eight characters long. You must specify
all eight characters even if the trailing characters are spaces.
The product ID can be up to 16 characters long.
scsi-vhci-failover-override =
"VendorID1ProductID1", "f_sym",
"VendorID2ProductID2", "f_sym",
...
"VendorIDnProductIDn", "f_sym";
Note that the entries are separated by the ’,’ character and the last vendor/product entry is
terminated by the ’;’ character.
For example, to add a device from a “ACME” vendor with a product ID of “MSU”, and to add a
device from vendor “XYZ” vendor with a product ID of “ABC”, you would add the following
lines to the /etc/driver/drv/scsi_vhci.conf file:
To add a device from a “XYZ” vendor with a product ID of “ABC”, you would add:
scsi-vhci-failover-override =
"ACME MSU", "f_sym",
"XYZ ABC", "f_sym";
Save and exit the /etc/driver/drv/scsi_vhci.conf file
For example,
scsi-vhci-failover-override =
"COMPELNTCompellent Vol", "f_sym";
# stmsboot -u
