PowerCLI pre zber dat

Pozdravujem vsetkych,

Zaujimavy tool pre generovanie PowerCLI skriptov pre zber dat z VMware infrastruktur.

Nedostupnost iSCSI LUNov v stave iSCSI software iniciatora Path Status Not used

Dnes som riesil problem s nedostupnostou iSCSI LUNov po restarte VMware ESXi. Konektivita vmkernel portu pre software iSCSI iniciator bola v poriadku. Session iSCSI bola nadviazana. Problem bol, ze v nastaveni iSCSI Initiator (vmhba39) --> Network Configuration bol Path Status v stave Not used a tym padom nebolo vidiet LUNy.

Problem som vyriesil nahranim pravidiel Pluggable Storage Architecture (PSA) pre spravu ciest na storage. Tu je command:

esxcli storage core claimrule load

Skript pre kontrolu a odpojenie CDROM na virtualoch

Tu je prakticky PowerCLI skript pre kontrolu stavu pripojenia CDROM virtualizovanych VMs:

Get-VM | Where-Object {$_ | Get-CDDrive |
    Where-Object { $_.ConnectionState.Connected -eq "true"  } } |
    Select-Object Name

Nasledne odpojenie CDROM virtualizovanych VMs cez PowerCLI skrip:

Get-VM | Where-Object {$_ | Get-CDDrive |
    Where-Object { $_.ConnectionState.Connected -eq "true"  } } |
    Get-CDDrive | Set-CDDrive -Connected $false -Confirm:$false

Ako pracuje Lockdown Mode

Pozdravujem vsetkych priaznivcov, po dlhsom case prispevok. Tentokrat clanky ohladne Lockdown Mode:

Virtual SAN – Maintenance Mode

Pozdravujem po dlhsom case!
Prezentujem link na zaujimavy scenar v ramci novej technologie Virtual SAN.
Ide konkretne o situaciu, ked potrebujeme dat ESXi host do tzv. Maintenance Mode.
