250 DS8000 Series: Concepts and Architecture
pwfile: passwd
# Default target Storage Image ID
# If the -dev parameter is needed in a command then it will default to the value here
# "devid" is equivalent to "-dev storage_image_ID"
# the default server that DS CLI commands will be run on is 2105 800 23953
devid: IBM.2105-23953
If you don’t want to create an encrypted password file, or do not have access to a simulator or
the real S-HMC, then you can specify the userid and password in plain text. This is done
either at the command line or in a script or in the profile. This is not recommended since the
password itself is now not as secure. An example of a profile that contains plain text
authentication details is shown in Example 11-16.
Example 11-16 Example of a DS CLI profile that specifies the username and password
#DS CLI Profile
# hmc1 is cluster 1 of 2105 800 23953
hmc1:10.0.0.1
#The username to log onto the ESS
username: csadmin
# The password for csadmin:
password: passw0rd
# Default target Storage Image ID
devid: IBM.2105-23953
An example of a command where the password is entered in plain text is shown in
Example 11-17. In this example the
lsuser command is issued directly to an S-HMC. Note
that the password will still be sent using SSL so a network sniffer would not be able to view it
easily. Note also that the syntax between the command and the profile is slightly different.
Example 11-17 Example of a DS CLI command that specifies the username and password
C:\Program Files\IBM\dscli>dscli -hmc1 10.0.0.1 -user admin -passwd passw0rd lsuser

Issuing a DS CLI command and scripting it
Having created a userid and preferably a password file, and then having edited the default
profile, it is now possible to issue DS CLI commands without logging onto the DS CLI
interpreter. An example is shown in Example 11-18.
Example 11-18 Establishing a FlashCopy with a single command
anthony@aixsrv:/opt/ibm/dscli > dscli mkflash -nocp 1004:1005
CMUC00137I mkflash: FlashCopy pair 1004:1005 successfully created.
exit status of dscli = 0
