Diagnostics and Troubleshooting Reference Manual – Virtual SAN Examples: controller slot=5 array A add drives=1:1-1:5 controller slot=5 array A add drives=1I:1:1,1I:1:2,1I:1:3 controller slot=5 array A add spares=allunassigned sparetype=autoreplace controller slot=5 array A add spares=2e:1:5 spareactivationmode=predictive ctrl slot=5 logicaldrive 1 add drives=1:8 controller slot=5 array A add drives=1I:1:1,1I:1:2,1I:1:3 modifyparitygroups=yes controller slot=1 array A add spares=1e:1:5 sparetype=dedicated controller slot=1 array A add spares=1e:1:5 sparetype=autoreplace controller slot=5 add licensekey=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX controller slot=5 add lk=XXXXXXXXXXXXXXXXXXXXXXXXX Now, this is not altogether intuitive to use so I recommend referring to HP Configuring Arrays on HP Smart Array Controllers Reference Guide to find the correct command syntax. The information provided from these commands may help you to determine if there are any underlying storage issues, and whether or not your controller has been configured optimally for Virtual SAN.

Diagnostics and Troubleshooting Reference Manual – Virtual SAN Controller & Disk Drive Information via hpssacli Let’s begin by getting a little bit more detail from the controllers. The first command here will just give us a brief description of the controller. esxcli hpssacli cmd -q "controller all show" ~ # esxcli hpssacli cmd -q "controller all show" Smart Array P410i in Slot 0 (Embedded) (sn: 5001438013072F30) Let’s run one more command to get the status of the controller only. esxcli hpssacli cmd -q "controller all show status" ~ # esxcli hpssacli cmd -q "controller all show status" Smart Array P410i in Slot 0 (Embedded) Controller Status: OK Cache Status: OK Battery/Capacitor Status: OK This next command provides a lot more detail. In particular, is the driver write cache disabled on the controller? As we can clearly seem it is. esxcli hpssacli cmd -q "controller slot=0 show" ~ # esxcli hpssacli cmd -q "controller slot=0 show" Smart Array P410i in Slot 0 (Embedded) Bus Interface: PCI Slot: 0 Serial Number: 5001438013072F30 Cache Serial Number: PBCDF0CRH0EIUW RAID 6 (ADG) Status: Disabled Controller Status: OK Hardware Revision: C Firmware Version: 3.66 Rebuild Priority: Medium Expand Priority: Medium Surface Scan Delay: 15 secs Surface Scan Mode: Idle Queue Depth: Automatic Monitor and Performance Delay: 60 min Elevator Sort: Enabled Degraded Performance Optimization: Disabled Inconsistency Repair Policy: Disabled Wait for Cache Room: Disabled Surface Analysis Inconsistency Notification: Disabled Post Prompt Timeout: 0 secs Cache Board Present: True Cache Status: OK V M W A R E S T O R A G E B U D O C U M E N T A T I O N / 2 7 9
