Symptoms



Large number of Severe log errors filling the ViPR SRM emc-vnx Collector logs. An example of the log errors is the following:

SEVERE     -- [2016-12-15 06:16:24 EST] -- DataListener$ValueFormatter::createValues(): Invalid value 'N/A' for key storagepool-tier-dataTargetedforHigherTier, context VNX4 and properties {topopass=value, getdisk-optional-speeds-flag=-speeds, getdisk-optional-usercapacity-flag=-usercapacity, getdisk-optional-busyticks_SPB-flag=-busyticks_SPB, storagepool-tier-freeCapacity=655.53, getdisk-optional-vendor-flag=-vendor, storagepool-tier-subscribed=90.00, getdisk-optional-hw-flag=-hw, storagepool-tier-consumedCapacity=5901.25, getdisk-optional-numluns-flag=-numluns, getdisk-optional-bytrd-flag=-bytrd, storagepool-tier-dgraid=r_10, secfilepath=, storagepool-tier-dataTargetedforLowerTier=N/A, userflag=-user, password={3E0405E9D4AE49A4ECF339796BDD4542A01749F85319EF7E1A2FA08AEEB331BFC81081913BFB861DEE24241CD99B####}, getdisk-optional-rev-flag=-rev, storagepool-freecapacity=11340.85693359375, nopollflag=-nopoll, getdisk-optional-product-flag=-product, agent-serialnb=CKM###########, RemoveMe=0, getlun-optional-que-flag=, getdisk-optional-drivetype-flag=-drivetype, agent-spb-memory=16384, storagepool-description=, agent-spa-memory=16384, storagepool-full=56.949, storagepool-tier-userCapacity=6556.78, isFlare33=true, storagepool-ddupefficiencysavings=, friendlyname=#######SAN01, spb=##.###.###.##, spa=##.###.###.##, getdisk-optional-arrivalswithnonzeroqueue-flag=-arrivalswithnonzeroqueue, agent-model=VNX5200, isFlare32=true, getdisk-optional-bytwrt-flag=-bytwrt, storagepool-ddupstat=, storagepool-fastcache=1, storagepool-ddupremainingsize=, array-setstats=ENABLED, getdisk-optional-sr-flag=-sr, getdisk-optional-que-flag=-que, <?xml version="1.0" encoding="UTF-8"?><sparql xmlns="http://www.w3.org/2005/sparql-results#">, storagepool-rawcapacity=40886.442401885986, secfilepathflag=, getdisk-optional-serial-flag=-serial, getdisk-optional-idleticks_SPB-flag=-idleticks_SPB, getdisk-optional-busyticks_SPA-flag=-busyticks_SPA, storagepool-ddupsharedcapacity=, storagepool-availability=Offline, scopeflag=-scope, getlun-optional-issnapmountpoint-flag=-issnapmountpoint, topouser=value, <variable name="issrc"/>, storagepool-part=RINPV06GP01, storagepool-tier-name=Performance, getdisk-optional-tla-flag=-tla, storagepool-disktype=Mixed, sstype=Block, cimauthorization=@{user}:@{password}:@{scope}, getdisk-optional-state-flag=-state, storagepool-subscribed=37120.60986328125, passwordflag=-password, getdisk-optional-hs-flag=-hs, storagepool-tier-dataTargetedforHigherTier=N/A, scope=0, zerovalue=0, getdisk-optional-sw-flag=-sw, getdisk-optional-capacity-flag=-capacity, storagepool-capacity=26342.8505859375, storagepool-dduppercentcompleted=, POLLING_COUNTER=2387, deviceid=4, command=/opt/Navisphere/bin/naviseccli, storagepool-subscribedcapacity=37120.60986328125, storagepool-dduplast=, getdisk-optional-hr-flag=-hr, getdisk-optional-idleticks_SPA-flag=-idleticks_SPA, topoport=######.###.###:48443, storagepool-raidtype=Mixed, getdisk-optional-wrts-flag=-wrts, storagepool-ddupstate=, storagepool-usedcapacity=15001.99365234375, storagepool-haslun=1, agent-revision=05.33.008.5.119, user=srm_service, getdisk-optional-rds-flag=-rds, getdisk-optional-rg-flag=-rg, storagepool-oversubscribedcapacity=10777.75927734375, getlun-optional-wcrh-flag=-wcrh}

Cause

The Stream-Collector cannot handle "N/A" values in the place of metrics and throws SEVERE errors when trying to cast "N/A" to a metric. On VNX, when a new Pool is created and the FAST VP relocation task has not been run at all, it causes "Data to move Up", "Data to move Down" and "Data to move within" to display N/A in NaviCLI/Unisphere.

Resolution

The following workaround can be performed to resolve the Severe log errors:

1) Backup /opt/APG/Collecting/Stream-Collector/emc-vnx/conf/transformers/normalizeAutotiering.xsl
2) Modify the file by doing the following:

Modify line 30
from:
<xsl:attribute name="datatoMoveWithinTiers" select="$storagePool[@NAME='Data to Move Within Tiers (GBs)']/VALUE" />

to:

<xsl:attribute name="datatoMoveWithinTiers" select="if ($storagePool[@NAME='Data to Move Within Tiers (GBs)']/VALUE !='N/A') then ($storagePool[@NAME='Data to Move Within Tiers (GBs)']/VALUE) else 0" /> 3) Backup /opt/APG/Collecting/Stream-Collector/emc-vnx/conf/transformers/vnxblock-storagepool.xsl 4) Modify the file by doing the following:

Modify lines 76 and 77
from:

<xsl:attribute name="dataTargetedforHigherTier" select="if (exists($tier[@NAME='Data Targeted for Higher Tier (GBs)'])) then ($tier[@NAME='Data Targeted for Higher Tier (GBs)']/VALUE) else 0" /> <xsl:attribute name="dataTargetedforLowerTier" select="if (exists($tier[@NAME='Data Targeted for Lower Tier (GBs)'])) then ($tier[@NAME='Data Targeted for Lower Tier (GBs)']/VALUE) else 0" /> to:

<xsl:attribute name="dataTargetedforHigherTier" select="if (exists($tier[@NAME='Data Targeted for Higher Tier (GBs)']) and $tier[@NAME='Data Targeted for Higher Tier (GBs)']/VALUE != 'N/A') then ($tier[@NAME='Data Targeted for Higher Tier (GBs)']/VALUE) else 0" /> <xsl:attribute name="dataTargetedforLowerTier" select="if (exists($tier[@NAME='Data Targeted for Lower Tier (GBs)']) and $tier[@NAME='Data Targeted for Lower Tier (GBs)']/VALUE != 'N/A') then ($tier[@NAME='Data Targeted for Lower Tier (GBs)']/VALUE) else 0" /> 5) Restart the collector, and verify that the error messages stop coming in.
