Password Complexity Override
In order to be able to change a user (or root) password to one that breaches password complexity checking
- Disable PAM module
esxcfg-auth --usepamqc -1 -1 -1 -1 -1 -1
- Disable complexity checker
esxcfg-auth --usecrack -1 -1 -1 -1 -1 -1
- Change password
- Re-enable PAM module
esxcfg-auth --usepamqc=-1 -1 -1 -1 8 8
HBA and SAN Operations
HBAnywhere Installation

HBA Firmware Upgrade
Requires HBAnywhere to be installed 1st, see HBAnywhere Installation for further info.
- Download the correct firmware version from Emulex's website
- EG for LPe11002's
- Extract, and copy file to server
- Find adapter's WWPN's
- EG
/usr/sbin/hbanyware/hbacmd ListHBAs
- EG
- Download new firware version to each HBA
- EG
/usr/sbin/hbanyware/hbacmd download 10:00:00:00:c9:82:97:9e zf280a4.all
- EG
EMCgrab Collection
- Download correct verion from EMC's website
- At time of writing the current version file was emcgrab_ESX_v1.1.tar

Vmkernel Log Analysis
Storage Monitor Log Entries
How to decode the following type of entries...
Sep 3 15:15:14 tfukesxent1 vmkernel: 85:01:23:01.532 cpu4:2264)StorageMonitor: 196: vmhba1:2:0:0 status = 2/0 0x6 0x2a 0x1 Sep 3 15:15:32 tfukesxent1 vmkernel: 85:01:23:19.391 cpu4:2253)StorageMonitor: 196: vmhba1:3:9:0 status = 2/0 0x6 0x2a 0x1

| 2 | Check Condition | Host_Busy_Busy |
| 3 | Host_Timeout | |
| 4 | Host_Bad_Target | |
| 5 | Host_Abort | |
| 6 | Host_Parity | |
| 7 | Host_Error | |
| 8 | Device Busy | Host_Reset |
| 9 | Host_Bad_INTR | |
| 10 | Host_PassThrough | |
| 11 | Host_Soft_Error | |
| 24 | Reservation Conflict |
Where the Sense Key mean...
| Hex | Sense Key |
|---|---|
| 0x0 | No Sense Information |
| 0x1 | Last command completed but used error correction |
| 0x2 | Unit Not Ready |
| 0x3 | Medium Error |

| 0xb | Aborted_Command - Target aborted command |
| 0xc | Comparison for SEARCH DATA unsuccessful |
| 0xd | Volume_Overflow - Medium is full |
| 0xe | Source and Data on Medium do not agree |
The Additional Sense Code and Additional Sense Code Qualifier mean
| Hex | Sense Code |
|---|---|
| 0x4 | Unit Not Ready |
