238 iSCSI CommandsSyntax• iscsi aging-time time• no iscsi aging-time• time — The number in minutes a session is not active prior to its removal. (Range: 1- 43,200)Default Configuration5 minutes.Command ModeGlobal Configuration mode.User Guidelines• All connections are measured in groups of 32. The aging time is the minimum time a connection'sactivity is measured deterministically. The actual aging may depend on the number of currentlymonitored connections, causing the activity to take longer. The result is 256 connections, which are allnot active, with an aging time of 5 minutes can be measured in 256/32 * 5min = 40 min. The aboveexample is a 'worst case' scenario.• Behavior when changing aging time:• When aging time is increased — Time for aging out current sessions is recalculated and increasedonly by the difference.• When aging time is decreased — Time for aging out current sessions will be decreased by thedifference. If after re-calculation, it is deemed that the session ‘silence’ time is already greater thanthe new aging time, the session will be immediately declared as aged-out.ExampleThe following example sets aging time for iSCSI sessions to 100 minutes.iscsi max connectionsThe iscsi max connections Global Configuration mode command sets the maximum number of iSCSIconnections that can be supported.
