Revision 578 – NetApp msosmsql Pseudo-Protocol Adds Fabric Suffix as HBA A/B

Posted on by

For a specific customer, I added a basic cut-n-paste customization of a different bnapsql:// or osmsql:// query that that appends the final character of the fabric nickname to the hostname and the WWPN such that hosts in “XX_FAB_A” or “XX_FAB_1” or “XX_FAB_a” become appended with “_A”; “_B”, “_2”, or “_b” become appended with “_B”. Anything else gets a “_X”.

This is done using a protocol “msosmsql”, for example:

java -jar vict.jar --nickname=msosmsql://server/

or

vict.bat -N msosmsql://server/

or since the customer has non-standard password (and the -n to store the result)

vict.bat -N msosmsql://user:pass@server/ -n A:\VirtualWisdomData\DeviceNickname\bna.csv

This allows a single query to produce nicknames on a different schema; also highlights a non-portability in the code that can be improved… but this is in production today. The customer’s response was “oh, that’s it? I thought that would be more difficult. How anti-climatic…” How can “easier than expected” be bad?

Revision 577 – servers.exclude should be discovery.exclude

Posted on by

Whitespace: due to discovery from an email thread, the detail of “the parameter in the properties file” slipped below an expert’s radar.

I therefore changed ~.vmware.servers.exclude to ~.vmware.discovery.exclude in the output of –dump-config=esx.csv output. Dion has indicated that this parameter is not length-limited, and has been tested with over 2000 entries.

This change is merely whitespace in the commentary of the generated file.

Revision 567 – VM Estimator via JNLP

Posted on by

Completed the VM Estimator but need to ensure it will deliver via JNLP. The VM Estimator is a simple GUI that can reach out and discover the ESX count on a vCenter. Currently only tested with https:// on a local 5.1 vCenter, seems to function. The key goal is to provide a quick estimate of the ESX counts of a number of vCenters in an organization to better estimate a rate-based cost where the number of ESX servers relates to a recurring license/usage/permit cost.

I’ll post a URL when it’s available.

Revision 564 – (weak) Suggested Nicknames for Dot Hill Systems Modular Storage Array

Posted on by

Expanded the option “-w” from Suggested Nicknames for Known WWN Patterns to vict.jar such that vict.jar -w 217000c0ff012345 shows “P2000-012345-A2” giving suggested nicknames to (HP -rebadged) Dot Hill Systems Modular Storage Array P2000. This WWN Descriptor is not very precise, but is empirically-based. Additional WWPN samples would help guide a better, more precise solution.

Revision 563 – TestCases

Posted on by

Few specific changes in this release, but a couple of little ones:

  1. In debugging some WBDCopyByFilter issues, some testcases were added for UDC2FilterLaconic and WBDCopyByFilterPrefixed which unfortunately show that the WBDs produced have the right filters applied, but no help in why the filters don’t appear in WBD
  2. version-bump to 3.4.4: VR grabs the newer version
  3. version-bump to 3.4.4: PortalHealthcheck knows the correct 3.4.4 DV to check against an ER-414

Revision 562 – Suggested Nicknames for Pillar SLM WWN Patterns

Posted on by

Expanded the option “-w” from Suggested Nicknames for Known WWN Patterns to vict.jar such that vict.jar -w 2100000b08123450 shows “Axiom-12345-c0p0” giving suggested nicknames to (Oracle) Pillar Axiom (SLM). This WWN Descriptor is not very precise, but is empirically-based. Additional WWPN samples would help guide a better, more precise solution.

Revision 560 – move FixNicknameHistory to VIFT

Posted on by

Per the conversation at SKO, the “–fixnicknamehistory” is the only art of VIClientTool (vict) that is a writeable action; otherwise, vict is read-only. In order to be sure that vict cannot hurt the database, the writeable portion of vict is moved back into the VIFieldTool (vift). vift is never left with a customer.

Revision 558 – phc-Nicknames.csv Offers Generated Nickname Suggestions

Posted on by

In revision 558, I added a logic to PHC that exercises the “-w” from Revision 555: VMax Nickname Suggestion back to Suggested Nicknames framework so that for missing nicknames, a phc-Nicknames.csv file attempts ot provide suggested nicknames for the WWNs of missing nicknames that it understands.

In short, PHC now provides suggestions for missing nicknames, making it possible to have nicknames for hosts the customer may not even be aware are visible by the VW Platform.
