Technical Notes

PowerPath and the CLARiiON admsnap Utility

Take note of the following if you use the CLARiiON admsnap utility

with PowerPath devices.

◆ For all versions of the admsnap utility, set the

PP_SHOW_CLAR_OWNING_SP environment variable to false to

suppress the display of default and current SP data:

PP_SHOW_CLAR_OWNING_SP=false

◆ For admsnap utility version 2.4.0.0.3 or less:

• Set the

PP_DEFAULT_STORAGE_SYS environment variable to

clariion to restrict the class of devices displayed by the

powermt utility to CLARiiON devices:

PP_DEFAULT_STORAGE_SYS=clariion

• Use a native PowerPath name (for example, /dev/sde) to start

or activate an

admsnap session when a file system is mounted

on a PowerPath device. You cannot use a PowerPath pseudo

device name (for example,

/dev/emcpowere) to start or

activate a session when a file system is mounted on a

PowerPath device.
