Custom SATP Claim Rule-Script for ESXi Host’s connecting to HPE 3PAR

Disclaimer:- The script below is from the Vmware community folks which is¬†tweaked a little to suit my purpose, Also please test before running in production. Reboot is required to claim the LUN’s.¬† FYI:- In certain cases, ¬†if the LUN is not RR already, running directly the Rule/script and rebooting the Host is not claiming the Read more about Custom SATP Claim Rule-Script for ESXi Host’s connecting to HPE 3PAR[…]

Network/Fibre issue’s on HP-BL-460C Gen9 Blades using CNA/FCOE in Redhat/Oracle OS.

¬† ¬† ¬† ¬† ¬† ¬†We recently had a¬†couple of issues configuring a HP BL 460 Gen9 blades with 536 FLb’s with SAN and Ethernet when using RedHat/Oracle 6.x/7.x OS versions. The issues happened with two different scenarios as below 1) When using Boot From SAN for the OS disk : ¬† ¬† ¬† ¬† Read more about Network/Fibre issue’s on HP-BL-460C Gen9 Blades using CNA/FCOE in Redhat/Oracle OS.[…]

ESXi 6.0U2 Storage issue’s with VV/PE LUN’s on HP-3Par

First of all thanks to the initial posts from below blogs that helped me to confirm and track the imminent storage issues that happened in our prod Cluster with 6.0U2 and HP-3Par.

1)

Max LUNs increased to 1024 in vSphere 6

2)

ESXi 6 Update 2, PDL errors on VVOL PE device

¬† ¬† ¬† ¬† ¬† ¬† ¬†Initially, ¬†the PE warnings/errors that are found with 6.0U2 ¬†with Hp-3Par¬†have been neglected ¬†assuming these are just some bunch of warnings with the LUN Number 256¬†that is visible from HP-3Par even though we are not using Virtual Volume Feature. But,¬†eventually these PE Lun’s have caused Production down when we tried to add new Datastores¬†which initiated a rescan and two ESXi hosts went to Hung state as they can’t handle how to deal with the more than a few seconds of I/O Latency.

¬† ¬† ¬† ¬† ¬† ¬†As mentioned by Virtual-Allan, this has been fixed in 3-Par by a FW patch, but ¬†interestingly HP never made this a recomended patch level. Also, this issue as mentioned is applicable to other storage arrays too that are presenting the PE LUN’s(Better to check for the anamolies during Rescan). Intrestingly we moved with changing the Max Disk Lun Setting to 250 in ESXi so that it can’t scan the¬†PE Lun until our Storage team fixes the issue.
