I get a timeout on iSCSI on different ESX hosts (3.5) at different times. It is puzzling, as both the ESX hosts as windows and other guests are experiencing timeouts.

The iSCSI network is segregated on a private network.

Here is an export of vmkiscsid.log from last night:

2010-02-10-12:30:38: iscsid: an InitiatorAlias= is required, but was not found in /etc/vmware/vmkiscsid/initiatorname.iscsi
2010-02-10-12:30:38: iscsid: LogLevel = 0
2010-02-10-12:30:38: iscsid: LogSync = 0
2010-02-10-12:30:42: iscsid: Login Success: iqn.1992-08.com.netapp:sn.101197719,default,192.168.73.2,3260,2001, 0x1
2010-02-10-12:30:42: iscsid: connection1:0 is operational now
2010-02-16-02:03:35: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3)
2010-02-16-02:03:39: iscsid: connection1:0 is operational after recovery (2 attempts)
2010-02-16-04:02:27: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3)
2010-02-16-04:02:32: iscsid: connection1:0 is operational after recovery (2 attempts)

Should i edit the timeout value on the ESX host for iSCSI? This may work around the problem but will not solve it.
