Enabling ALUA (alua_enabled)

ALUA is supported by HP-UX11iv3 Sep 2007 ver. or later.
If the OS supporting ALUA is used, check the "alua_enabled" setting and set it to "true" if it is not.
1
Check whether the OS supports ALUA.
To check whether the OS supports ALUA, use the "scsimgr" command and check existence of the
"alua_enabled" attribute.
Example of OS supporting ALUA
# scsimgr get_attr | grep alua_enabled
name = alua_enabled
If executing the command displays nothing, the OS does not support ALUA. In this case, the operations
described below are not required.
2
Check the "alua_enabled" setting.
Use the "scsimgr" command to check the "alua_enabled" attribute for each LUN.
Execute the command for all LUNs in the ETERNUS DX.
Example for checking the "alua_enabled" setting
# scsimgr get_attr -D /dev/rdisk/disk25 -a alua_enabled
name = alua_enabled
current = true
default = true
saved = true
If "current" and "saved" are indicated as "true", ALUA is already enabled. In this case, the operations
described below are not required.
3
Set "alua_enabled".
Use the "scsimgr" command to set the "alua_enabled" attribute to "true" for each LUN.
Example for setting "alua_enabled"
# scsimgr save_attr -D /dev/rdisk/disk25 -a alua_enabled=true
Value of attribute alua_enabled saved successfully
