HP 3PAR T-Class Installation and Deinstallation Guide

7. Monitor the progress of startnoderescue by using the showtask CLI command.
a. Look for the ID number of the most recent node_rescue task, which is usually at the
bottom of the list. That task-ID will be used below. For example:
cli% showtask
Id Type Name Status Phase Step ----StartTime------ FinishTime Priority- ---User----
2488 node_rescue node_0_rescue active 1/1 0/1 2012-12-03 15:18 PST - n/a sys:3parsy
NOTE: Depending on the number of adapters and amount of memory in the node, the
node could take 10-20 minutes before it becomes part of the system.
b. Enter showtask -d task-ID to see the current and detailed status of the node_rescue
operation. For example:
cli% showtask -d 2488
Id Type Name Status Phase Step ------StartTime----- -FinishTime- -Priority- ---User--
248 node_rescue node_0_rescue active 1/1 0/1 2012-12-03 15:18 PST - n/a sys:3parsy
