Hello all...
| H:0x2 | BUS stayed busy through time out period |
| H:0x8 | The SCSI bus (or this device) has been reset. Any SCSI device on a SCSI bus is capable of instigating a reset. |
| D:0x2 | CHECK CONDITION |
| h:0xc | This status is returned due to a transient error. When this status is returned, the I/O command is requeued and issued again. |
Been noodling on these entries for awhile now :

we even get H:0x8 and H:0xc as well as D:0x2:
Are these normal ? given that in 1 vmKernel log file we get over 400 H:0x2 entries in one host...we have 4 currently.
Does this mean our SAN / SVC is unable to accomodate the load?
or Could there be something in vmware/vcenter v5.1 esx 5.1 that we can configure/upgrade/
are these entries probable/ or actual cause for VMs freezing/slowing down for 15secs or more ?
please advise...
thank you,
Kahlil
